MusicBrainz is a project that aims to create an open data music database, similar to the freedb project. MusicBrainz was founded in response to the restrictions placed on the Compact Disc Database, a database for software applications to look up audio CD information on the Internet. MusicBrainz has expanded its goals to reach beyond a compact disc metadata storehouse to become a structured open online database for music. MusicBrainz captures information about artists, their recorded works, the relationships between them. Recorded works entries capture at a minimum the album title, track titles, the length of each track; these entries are maintained by volunteer editors. Recorded works can store information about the release date and country, the CD ID, cover art, acoustic fingerprint, free-form annotation text and other metadata; as of 21 September 2018, MusicBrainz contained information about 1.4 million artists, 2 million releases, 19 million recordings. End-users can use software that communicates with MusicBrainz to add metadata tags to their digital media files, such as FLAC, MP3, Ogg Vorbis or AAC.
MusicBrainz allows contributors to upload cover art images of releases to the database. Internet Archive provides the bandwidth and legal protection for hosting the images, while MusicBrainz stores metadata and provides public access through the web and via an API for third parties to use; as with other contributions, the MusicBrainz community is in charge of maintaining and reviewing the data. Cover art is provided for items on sale at Amazon.com and some other online resources, but CAA is now preferred because it gives the community more control and flexibility for managing the images. Besides collecting metadata about music, MusicBrainz allows looking up recordings by their acoustic fingerprint. A separate application, such as MusicBrainz Picard, must be used for this. In 2000, MusicBrainz started using Relatable's patented TRM for acoustic fingerprint matching; this feature allowed the database to grow quickly. However, by 2005 TRM was showing scalability issues as the number of tracks in the database had reached into the millions.
This issue was resolved in May 2006 when MusicBrainz partnered with MusicIP, replacing TRM with MusicDNS. TRMs were phased out and replaced by MusicDNS in November 2008. In October 2009 MusicIP was acquired by AmpliFIND; some time after the acquisition, the MusicDNS service began having intermittent problems. Since the future of the free identification service was uncertain, a replacement for it was sought; the Chromaprint acoustic fingerprinting algorithm, the basis for AcoustID identification service, was started in February 2010 by a long-time MusicBrainz contributor Lukáš Lalinský. While AcoustID and Chromaprint are not MusicBrainz projects, they are tied with each other and both are open source. Chromaprint works by analyzing the first two minutes of a track, detecting the strength in each of 12 pitch classes, storing these 8 times per second. Additional post-processing is applied to compress this fingerprint while retaining patterns; the AcoustID search server searches from the database of fingerprints by similarity and returns the AcoustID identifier along with MusicBrainz recording identifiers if known.
Since 2003, MusicBrainz's core data are in the public domain, additional content, including moderation data, is placed under the Creative Commons CC-BY-NC-SA-2.0 license. The relational database management system is PostgreSQL; the server software is covered by the GNU General Public License. The MusicBrainz client software library, libmusicbrainz, is licensed under the GNU Lesser General Public License, which allows use of the code by proprietary software products. In December 2004, the MusicBrainz project was turned over to the MetaBrainz Foundation, a non-profit group, by its creator Robert Kaye. On 20 January 2006, the first commercial venture to use MusicBrainz data was the Barcelona, Spain-based Linkara in their Linkara Música service. On 28 June 2007, BBC announced that it has licensed MusicBrainz's live data feed to augment their music Web pages; the BBC online music editors will join the MusicBrainz community to contribute their knowledge to the database. On 28 July 2008, the beta of the new BBC Music site was launched, which publishes a page for each MusicBrainz artist.

Croatia the Republic of Croatia, is a country at the crossroads of Central and Southeast Europe, on the Adriatic Sea. It borders Slovenia to the northwest, Hungary to the northeast, Serbia to the east and Herzegovina, Montenegro to the southeast, sharing a maritime border with Italy, its capital, forms one of the country's primary subdivisions, along with twenty counties. Croatia has an area of 56,594 square kilometres and a population of 4.28 million, most of whom are Roman Catholics. Inhabited since the Paleolithic Age, the Croats arrived in the area in the 6th century and organised the territory into two duchies by the 9th century. Croatia was first internationally recognized as an independent state on 7 June 879 during the reign of duke Branimir. Tomislav became the first king by 925, elevating Croatia to the status of a kingdom, which retained its sovereignty for nearly two centuries. During the succession crisis after the Trpimirović dynasty ended, Croatia entered a personal union with Hungary in 1102.
In 1527, faced with Ottoman conquest, the Croatian Parliament elected Ferdinand I of Austria to the Croatian throne. In October 1918, in the final days of World War I, the State of Slovenes and Serbs, independent from Austria-Hungary, was proclaimed in Zagreb, in December 1918 it was merged into the Kingdom of Serbs and Slovenes. Following the Axis invasion of Yugoslavia in April 1941, most of the Croatian territory was incorporated into the Nazi-backed client-state which led to the development of a resistance movement and the creation of the Federal State of Croatia which after the war become a founding member and a federal constituent of the Socialist Federal Republic of Yugoslavia. On 25 June 1991, Croatia declared independence, which came wholly into effect on 8 October of the same year; the Croatian War of Independence was fought for four years following the declaration. The sovereign state of Croatia is a republic governed under a parliamentary system and a developed country with a high standard of living.
It is a member of the European Union, the United Nations, the Council of Europe, NATO, the World Trade Organization, a founding member of the Union for the Mediterranean. As an active participant in the UN peacekeeping forces, Croatia has contributed troops to the NATO-led mission in Afghanistan and took a non-permanent seat on the UN Security Council for the 2008–2009 term. Since 2000, the Croatian government has invested in infrastructure transport routes and facilities along the Pan-European corridors. Croatia's economy is dominated by service and industrial sectors and agriculture. Tourism is a significant source of revenue, with Croatia ranked among the top 20 most popular tourist destinations in the world; the state controls a part of the economy, with substantial government expenditure. The European Union is Croatia's most important trading partner. Croatia provides a social security, universal health care system, a tuition-free primary and secondary education, while supporting culture through numerous public institutions and corporate investments in media and publishing.
The name of Croatia derives from Medieval Latin Croātia. Itself a derivation of North-West Slavic *Xrovat-, by liquid metathesis from Common Slavic period *Xorvat, from proposed Proto-Slavic *Xъrvátъ which comes from Old Persian *xaraxwat-; the word is attested by the Old Iranian toponym Harahvait-, the native name of Arachosia. The origin of the name is uncertain, but is thought to be a Gothic or Indo-Aryan term assigned to a Slavic tribe; the oldest preserved record of the Croatian ethnonym *xъrvatъ is of variable stem, attested in the Baška tablet in style zvъnъmirъ kralъ xrъvatъskъ. The first attestation of the Latin term is attributed to a charter of Duke Trpimir from the year 852; the original is lost, just a 1568 copy is preserved, leading to doubts over the authenticity of the claim. The oldest preserved stone inscription is the 9th-century Branimir Inscription found near Benkovac, where Duke Branimir is styled Dux Cruatorvm; the inscription is not believed to be dated but is to be from during the period of 879–892, during Branimir's rule.
The area known as Croatia today was inhabited throughout the prehistoric period. Fossils of Neanderthals dating to the middle Palaeolithic period have been unearthed in northern Croatia, with the most famous and the best presented site in Krapina. Remnants of several Neolithic and Chalcolithic cultures were found in all regions of the country; the largest proportion of the sites is in the river valleys of northern Croatia, the most significant cultures whose presence was discovered include Baden, Starčevo, Vučedol cultures. The Iron Age left traces of the Celtic La Tène culture. Much the region was settled by Illyrians and Liburnians, while the first Greek colonies were established on the islands of Hvar, Korčula, Vis. In 9 AD the territory of today's Croatia became part of the Roman Empire. Emperor Diocletian had a large palace built in Split to which he retired after his abdication in AD 305. During the 5th century, the last de jure Western emperor last Western Roman Emperor Julius Nepos ruled his small realm from the palace after fleeing Italy to go into exile in 475.
The period ends with Avar and Croat invasions in the first half of the 7th century and destruction of all Roman towns. Roman survivors retreated to more favourable sites on the coast and mountains; the city of Dubrovnik was founded by such survivors from Epidaurum. The ethnogenesis of Croats is uncertain an
Zagreb is the capital and the largest city of Croatia. It is located in the northwest of the country, along the Sava river, at the southern slopes of the Medvednica mountain. Zagreb lies at an elevation of 122 m above sea level; the estimated population of the city in 2018 is 810,003. The population of the Zagreb urban agglomeration is about 1.2 million a quarter of the total population of Croatia. Zagreb is a city with a rich history dating from the Roman times to the present day; the oldest settlement located in the vicinity of the city was the Roman Andautonia, in today's Ščitarjevo. The name "Zagreb" is recorded in 1134, in reference to the foundation of the settlement at Kaptol in 1094. Zagreb became a free royal town in 1242. In 1851 Zagreb had Janko Kamauf. Zagreb has special status as a Croatian administrative division and is a consolidated city-county, is administratively subdivided into 17 city districts. Most of them are at a low elevation along the river Sava valley, whereas northern and northeastern city districts, such as Podsljeme and Sesvete districts are situated in the foothills of the Medvednica mountain, making the city's geographical image rather diverse.
The city extends over 30 kilometres east-west and around 20 kilometres north-south. The transport connections, concentration of industry and research institutions and industrial tradition underlie its leading economic position in Croatia. Zagreb is the seat of the central government, administrative bodies, all government ministries. All of the largest Croatian companies and scientific institutions have their headquarters in the city. Zagreb is the most important transport hub in Croatia where Central Europe, the Mediterranean and Southeast Europe meet, making the Zagreb area the centre of the road and air networks of Croatia, it is a city known for its diverse economy, high quality of living, museums and entertainment events. Its main branches of economy are the service sector; the etymology of the name Zagreb is unclear. It was used for the united city only from 1852, but it had been in use as the name of the Zagreb Diocese since the 12th century, was used for the city in the 17th century; the name is first recorded in a charter by Ostrogon archbishop Felician, dated 1134, mentioned as Zagrabiensem episcopatum.
The older form of the name is Zagrab. The modern Croatian form Zagreb is first recorded in a 1689 map by Nicolas Sanson. An older form is reflected in Hungarian Zabrag. For this, Hungarian linguist Gyula Décsy proposes the etymology of Chabrag, a well-attested hypocorism of the name Cyprian; the same form is reflected in a number such as Csepreg. The name might be derived from Proto-Slavic word * grębъ which means uplift. An Old Croatian reconstructed name *Zagrębъ is manifested through the German name of the city Agram; the name Agram was used in German in the Habsburg period. In Middle Latin and Modern Latin, Zagreb is known as Zagrabia or Mons Graecensis. In Croatian folk etymology, the name of the city has been derived from either the verb za-grab-, meaning "to scoop" or "to dig". One folk legend illustrating this derivation ties the name to a drought of the early 14th century, during which Augustin Kažotić is said to have dug a well which miraculously produced water. In another legend, a city governor is thirsty and orders a girl named Manda to "scoop" water from Manduševac well, using the imperative: zagrabi, Mando!.
The oldest settlement located near today's Zagreb was a Roman town of Andautonia, now Šćitarjevo, which existed between the 1st and the 5th century AD. The first recorded appearance of the name Zagreb is dated to 1094, at which time the city existed as two different city centres: the smaller, eastern Kaptol, inhabited by clergy and housing Zagreb Cathedral, the larger, western Gradec, inhabited by craftsmen and merchants. Gradec and Kaptol were united in 1851 by ban Josip Jelačić, credited for this, with the naming the main city square, Ban Jelačić Square in his honour. During the period of former Yugoslavia, Zagreb remained an important economic centre of the country, was the second largest city. After Croatia declared independence from Yugoslavia, Zagreb was proclaimed its capital; the history of Zagreb dates as far back as 1094 A. D. when the Hungarian King Ladislaus, returning from his campaign against Croatia, founded a diocese. Alongside the bishop's see, the canonical settlement Kaptol developed north of Zagreb Cathedral, as did the fortified settlement Gradec on the neighbouring hill.
Today the latter is one of the best preserved urban nuclei in Croatia. Both settlements came under Tatar attack in 1242; as a sign of gratitude for offering him a safe haven from the Tatars the Croatian and Hungarian King Bela IV bestowed Gradec with a Golden Bull, which offered its citizens exemption from county rule and
Virtual International Authority File
The Virtual International Authority File is an international authority file. It is a joint project of several national libraries and operated by the Online Computer Library Center. Discussion about having a common international authority started in the late 1990s. After a series of failed attempts to come up with a unique common authority file, the new idea was to link existing national authorities; this would present all the benefits of a common file without requiring a large investment of time and expense in the process. The project was initiated by the US Library of Congress, the German National Library and the OCLC on August 6, 2003; the Bibliothèque nationale de France joined the project on October 5, 2007. The project transitioned to being a service of the OCLC on April 4, 2012; the aim is to link the national authority files to a single virtual authority file. In this file, identical records from the different data sets are linked together. A VIAF record receives a standard data number, contains the primary "see" and "see also" records from the original records, refers to the original authority records.
The data are available for research and data exchange and sharing. Reciprocal updating uses the Open Archives Initiative Protocol for Metadata Harvesting protocol; the file numbers are being added to Wikipedia biographical articles and are incorporated into Wikidata. VIAF's clustering algorithm is run every month; as more data are added from participating libraries, clusters of authority records may coalesce or split, leading to some fluctuation in the VIAF identifier of certain authority records.

Hip hop music
Hip hop music called hip-hop or rap music, is a music genre developed in the United States by inner-city African Americans in the late 1970s which consists of a stylized rhythmic music that accompanies rapping, a rhythmic and rhyming speech, chanted. It developed as part of hip hop culture, a subculture defined by four key stylistic elements: MCing/rapping, DJing/scratching with turntables, break dancing, graffiti writing. Other elements include sampling beats or bass lines from records, rhythmic beatboxing. While used to refer to rapping, "hip hop" more properly denotes the practice of the entire subculture; the term hip hop music is sometimes used synonymously with the term rap music, though rapping is not a required component of hip hop music. Hip hop as both a musical genre and a culture was formed during the 1970s when block parties became popular in New York City among African-American youth residing in the Bronx; however hip-hop music did not get recorded for the radio or television to play until 1979 due to poverty during hip-hop's birth and lack of acceptance outside ghetto neighborhoods.
At block parties DJs played percussive breaks of popular songs using two turntables and a DJ mixer to be able to play breaks from two copies of the same record, alternating from one to the other and extending the "break". Hip hop's early evolution occurred as sampling technology and drum machines became available and affordable. Turntablist techniques such as scratching and beatmatching developed along with the breaks and Jamaican toasting, a chanting vocal style, was used over the beats. Rapping developed as a vocal style in which the artist speaks or chants along rhythmically with an instrumental or synthesized beat. Notable artists at this time include DJ Kool Herc, Grandmaster Flash and The Furious Five, Fab Five Freddy, Marley Marl, Afrika Bambaataa, Kool Moe Dee, Kurtis Blow, Doug E. Fresh, Warp 9, The Fat Boys, Spoonie Gee; the Sugarhill Gang's 1979 song "Rapper's Delight" is regarded to be the first hip hop record to gain widespread popularity in the mainstream. The 1980s marked the diversification of hip hop.
Prior to the 1980s, hip hop music was confined within the United States. However, during the 1980s, it began to spread to music scenes in dozens of countries, many of which mixed hip hop with local styles to create new subgenres. New school hip hop was the second wave of hip hop music, originating in 1983–84 with the early records of Run-D. M. C. and LL Cool J. The Golden age hip hop period was an innovative period between the early 1990s. Notable artists from this era include the Juice Crew, Public Enemy, Eric B. & Rakim, Boogie Down Productions and KRS-One, EPMD, Slick Rick, Beastie Boys, Kool G Rap, Big Daddy Kane, Ultramagnetic MCs, De La Soul, A Tribe Called Quest. Gangsta rap is a subgenre of hip hop that focuses on the violent lifestyles and impoverished conditions of inner-city African-American youth. Schoolly D, N. W. A, Ice-T, Ice Cube, the Geto Boys are key founding artists, known for mixing the political and social commentary of political rap with the criminal elements and crime stories found in gangsta rap.
In the West Coast hip hop style, G-funk dominated mainstream hip hop for several years during the 1990s with artists such as Dr. Dre and Snoop Dogg. East Coast hip hop in the early to mid 1990s was dominated by the Afrocentric jazz rap and alternative hip hop of the Native Tongues posse as well as the hardcore rap of artists such as Mobb Deep, Wu-Tang Clan, Onyx. East Coast hip hop had gangsta rap musicians such as Kool G Rap and the Notorious B. I. G.. In the 1990s, hip hop began to diversify with other regional styles emerging, such as Southern rap and Atlanta hip hop. At the same time, hip hop continued to be assimilated into other genres of popular music, examples being neo soul and nu metal. Hip hop became a best-selling genre in the mid-1990s and the top selling music genre by 1999; the popularity of hip hop music continued through the 2000s, with hip hop influences increasingly finding their way into mainstream pop. The United States saw the success of regional styles such as crunk, a Southern genre that emphasized the beats and music more than the lyrics.
Starting in 2005, sales of hip hop music in the United States began to wane. During the mid-2000s, alternative hip hop secured a place in the mainstream, due in part to the crossover success of artists such as OutKast and Kanye West. During the late 2000s and early 2010s, rappers such as Lil Wayne, Soulja Boy, B.o. B were the most popular rappers. During the 2010s, rappers such as Drake, Nicki Minaj, J. Cole, Kendrick Lamar all have been popular. Trap, a subgenre of hip hop has been popular during the 2010s with hip hop artists and hip hop music groups such as Migos, Travis Scott, Kodak Black; the creation of the term hip hop is credited to Keith Cowboy, rapper with Grandmaster Flash and the Furious Five. However, Lovebug Starski, Keith Cowboy, DJ Hollywood used the term when the music was still known as disco rap, it is believed that Cowboy created the term while teasing a friend who had just joined the U. S. Army, by scat singing the words "hip/hop/hip/hop" in a way that mimicked the rhythmic cadence of soldiers marching.
Cowboy worked the "hip hop" cadence into a part of his stage performance, used by other artists such as The Sugarhi
Ohrid is a city in North Macedonia, the seat of Ohrid Municipality. It is the largest city on Lake Ohrid and the eighth-largest city in the country, with over 42,000 inhabitants as of 2002. Ohrid once had 365 churches, one for each day of the year, has been referred to as a "Jerusalem"; the city is rich in picturesque houses and monuments, tourism is predominant. It is located southwest of west of Resen and Bitola. In 1979 and in 1980 Ohrid and Lake Ohrid were accepted as Cultural and Natural World Heritage Sites by UNESCO. Ohrid is one of only 28 sites that are part of UNESCO's World Heritage that are Cultural as well as Natural sites. In antiquity the city was known under the ancient Greek name of Λυχνίς and Λυχνιδός and the Latin Lychnidus meaning "city of light" "a precious stone that emits light", from λύχνος, "lamp, portable light". Polybius, writing in the second century BC, refers to the town as Λυχνίδιον - Lichnidion, it became capital of the First Bulgarian Empire in the early medieval period, was referred to by Byzantine writers as Achrida.
By 879 AD, the town was referred to as Ohrid. In Macedonian language and the other South Slavic languages, the name of the city is Ohrid. In Albanian, the city is known in modern Greek Ochrida and Achrida; the earliest inhabitants of the widest Lake Ohrid region were the Enchele, an Illyrian tribe and the Dassaretae, an ancient Greek tribe based further East in the region of Lynkestis. According to recent excavations this was a town as early as of king Phillip II of Macedon, they conclude that Samuil's Fortress was built on the place of an earlier fortification, dated to 4th century BC. During the Roman conquests, towards the end of 3rd and the beginning of 2nd century BC, the Dassaretae and the region Dassaretia were mentioned, as well as the ancient Greek city of Lychnidos; the existence of the ancient Greek city of Lychnidos is linked to the Greek myth of the Phoenician prince Cadmus who, banished from Thebes, in Boeotia, fled to the Enchele and founded the town of Lychnidos on the shores of the modern Lake Ohrid.
The Lake of Ohrid, the ancient Greek Lacus Lychnitis, whose blue and exceedingly transparent waters in antiquity gave to the lake its Greek name. It was located along the Via Egnatia. Archaeological excavations prove early adoption of Christianity in the area. Bishops from Lychnidos participated in multiple ecumenical councils; the South Slavs began to arrive in the area during the 6th century AD. By the early 7th century it was colonized by a Slavic tribe known as the Berziti. Bulgaria conquered the city around 840; the name Ohrid first appeared in 879. The Ohrid Literary School established in 886 by Clement of Ohrid became one of the two major cultural centres of the First Bulgarian Empire. Between 990 and 1015, Ohrid was the stronghold of the Bulgarian Empire. From 990 to 1018 Ohrid was the seat of the Bulgarian Patriarchate. After the Byzantine reconquest of the city in 1018 by Basil II, the Bulgarian Patriarchate was downgraded to an Archbishopric of Ohrid, placed under the authority of the Ecumenical Patriarch of Constantinople.
The higher clergy after 1018 was invariably Greek, including during the period of Ottoman domination, until the abolition of the archbishopric in 1767. At the beginning of the 16th century the archbishopric reached its peak subordinating the Sofia, Vidin and Moldavian eparchies, part of the former medieval Serbian Patriarchate of Peć, the Orthodox districts of Italy and Dalmatia; as an episcopal city, Ohrid was a cultural center of great importance for the Balkans. All surviving churches were built by the Byzantines and by the Bulgarians, the rest of them date back to the short time of Serbian rule during the late Middle Ages. Bohemond, leading a Norman army from southern Italy, took the city in 1083. Byzantines regained it in 1085. In the 13th and 14th century the city changed hands between the Despotate of Epirus, the Bulgarian, the Byzantine and the Serbian Empires, as well as local Albanian rulers. In the mid-13th century Ohrid was one of the cities ruled by Pal Gropa, a member of the Albanian noble Gropa family.
In 1334 the city was incorporated in the Serbian Empire. After Dusan's death the city came under the control of Andrea Gropa, while after his death Prince Marko incorporated it in the Kingdom of Prilep. In the early 1370s Marko lost Ohrid to Pal II Gropa, another member of the Gropa family and unsuccessfully tried to recapture it in 1375 with Ottoman assistance. In 1395 the Ottomans under Bayezid I captured the city which became the seat of the newly established Sanjak of Ohrid. In September 14–15, 1464 12,000 troops of the League of Lezhë and 1,000 of the Republic of Venice defeated a 14,000-man Ottoman force near the city; when Mehmed II returned from Albania after his actions against Skanderbeg in 1466 he dethroned Dorotheos, the Archbishop of Ohrid, expatriated him together with his clerks and boyars and considerable number of citizens of Ohrid to Istanbul because of their anti-Ottoman activities during Skanderbeg's rebellion when many citizens of Ohrid, including Dorotheos and his clergy, supported Skanderbeg and his fight.
The Christian population declined during the first centuries of Ottoman rule. In 1664 there w
