I dump dei dati sono una versione scaricabile dei dati in Freebase. Costituiscono uno snapshot dei dati archiviati in Freebase e dello schema che li struttura e vengono forniti con la stessa licenza CC-BY. I mapping Freebase/Wikidata sono forniti ai sensi della licenza CC0.
Se scrivi il tuo codice per analizzare i dump RDF, spesso è più efficiente leggere direttamente dal file GZip anziché estrarre prima i dati e poi elaborare i dati decompressi.
<subject> <predicate> <object> .
Nota: in Freebase, gli oggetti hanno MID simili a /m/012rkqx. In RDF questi ID diventano m.012rkqx. Allo stesso modo, lo schema Freebase come /common/topic viene scritto come common.topic.
Il soggetto è l'ID di un oggetto Freebase. Può essere un MID Freebase (ad es. m.012rkqx) per argomenti e CVT o un ID leggibile (ad es. common.topic) per lo schema.
Il predicato è sempre un ID leggibile da una persona per una proprietà Freebase o una proprietà di un vocabolario RDF standard come RDFS. Gli spazi dei nomi delle chiavi esterne di Freebase vengono utilizzati anche come predicati per semplificare la ricerca delle chiavi per spazio dei nomi.
Il campo dell'oggetto può contenere un MID Freebase per un oggetto o un ID leggibile per lo schema di Freebase o altri vocabolari RDF. Può includere anche valori letterali come stringhe, valori booleani e numerici.
Le descrizioni degli argomenti spesso contengono caratteri di fine riga. Per fare in modo che ogni tripla rientri in una riga, abbiamo eseguito l'escape dei caratteri di nuova riga con "\n".
Freebase Deleted Triples
Forniamo anche un dump delle triple che sono state eliminate da Freebase nel tempo. Si tratta di un dump una tantum fino a marzo 2013. In futuro potremmo prendere in considerazione la possibilità di fornire aggiornamenti periodici delle triple eliminate di recente, ma al momento non abbiamo una tempistica specifica per farlo e forniamo solo questo dump una tantum.
Il dump viene distribuito come file .tar.gz (2,1 GB compresso, 7,7 GB non compresso). Contiene 63.036.271 triple eliminate in 20 file (i singoli file non hanno un significato particolare, è solo più facile manipolare diversi file più piccoli rispetto a un unico file enorme).
Grazie a Chun How Tan e John Giannandrea per aver reso possibile il rilascio di questi dati.
Il formato dei dati è essenzialmente CSV con un'importante avvertenza. Il campo dell'oggetto può contenere qualsiasi carattere, comprese le virgole (e qualsiasi altro delimitatore ragionevole che ti venga in mente). Tuttavia, è garantito che tutti gli altri campi non contengano virgole, quindi i dati possono comunque essere analizzati in modo non ambiguo.
Le colonne nel set di dati sono definite come segue:
creation_timestamp (tempo Unix in millisecondi)
creator
deletion_timestamp (tempo Unix in millisecondi)
eliminatore
soggetto (MID)
predicato (MID)
oggetto (MID/letterale)

Mappature Freebase/Wikidata
I dati sono stati creati in base al dump di Wikidata del 28 ottobre 2013 e contengono solo i link che hanno almeno due link di Wikipedia in comune e non un singolo link di Wikipedia in disaccordo. Inoltre, le righe sono ordinate in base al numero di link di Wikipedia comuni (anche se in Turtle questo non ha molta importanza).
I dump di dati di Freebase vengono forniti senza costi per qualsiasi scopo con aggiornamenti regolari da parte di Google. Come Freebase, sono distribuiti con licenza Creative Commons Attribution (CC-BY) e l'utilizzo è soggetto ai Termini di servizio.
I mapping degli ID Freebase/Wikidata sono forniti ai sensi della licenza CC0 e possono essere utilizzati senza limitazioni.

In RDF those MIDs become m.012rkqx. Likewise, Freebase schema like `/common/topic` are written as `common.topic`.\n\nThe *subject* is the ID of a Freebase object. It can be a Freebase MID (ex. m.012rkqx) for topics and CVTs or a human-readable ID (ex. `common.topic`) for schema.\n\nThe *predicate* is always a human-readable ID for a Freebase property or a property from a standard RDF vocabulary like [RDFS](https://en.wikipedia.org/wiki/RDFS). Freebase foreign key namespaces are also used as predicates to make it easier to look up keys by namespace.\n\nThe object field may contain a Freebase MID for an object or a human-readable ID for schema from Freebase or other RDF vocabularies. It may also include literal values like strings, booleans and numeric values.\n\nTopic descriptions often contain newlines. In order to make each triple fit on one line, we have escaped newlines with \"\\\\n\".\n\nFreebase Deleted Triples\n------------------------\n\nWe also provide a dump of triples that have been deleted from Freebase over time. This is a one-time dump through March 2013. In the future, we might consider providing periodic updates of recently deleted triples, but at the moment we have no specific timeframe for doing so, and are only providing this one-time dump.\n\nThe dump is distributed as a .tar.gz file (2.1Gb compressed, 7.7Gb uncompressed). It contains 63,036,271 deleted triples in 20 files (there is no particular meaning to the individual files, it is just easier to manipulate several smaller files than one huge file).\n\n\nThanks to Chun How Tan and John Giannandrea for making this data release possible.\n\n|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------|----------|\n| - **Total triples:** 63 million - **Updated:** June 9, 2013 - **Data Format:** [CSV](https://en.wikipedia.org/wiki/Comma-separated_values) - **License:** [CC-BY](https://creativecommons.org/licenses/by/2.5/) | **2 GB** gzip **8 GB** uncompressed | Download |\n\nThe data format is essentially CSV with one important caveat. The object field may contain any characters, including commas (as well as any other reasonable delimiters you could think of). However, all the other fields are guaranteed not to contain commas, so the data can still be parsed unambiguously.\n\nThe columns in the dataset are defined as:\n\n- creation_timestamp (Unix epoch time in milliseconds)\n- creator\n- deletion_timestamp (Unix epoch time in milliseconds)\n- deletor\n- subject (MID)\n- predicate (MID)\n- object (MID/Literal)\n- language_code\n\nCSV \n\n```\n1352854086000,/user/mwcl_wikipedia_en,1352855856000,/user/mwcl_wikipedia_en,/m/03r90,/type/object/key,/wikipedia/en/$B816,en\n1355171076000,/user/mwcl_musicbrainz,1364258198000,/user/turtlewax_bot,/m/0nncp9z,/music/recording/artist,/m/01vbfm4,en\n1176630380000,/user/mwcl_images,1335928144000,/user/gardening_bot,/m/029w57m,/common/image/size,/m/0kly56,en\n1292854917000,/user/mwcl_musicbrainz,1364823418001,/user/mbz_pipeline_merge_bot,/m/0fv1vl8,/type/object/type,/common/topic,en\n1205530905000,/user/mwcl_images,1336022041000,/user/gardening_bot,/m/01x5scz,/common/licensed_object/license,/m/02x6b,en\n1302391361000,/user/content_administrator,1336190973000,/user/gardening_bot,/m/0gkb45y,/type/object/type,/type/content,en\n1176728962002,/user/mwcl_images,1335954186000,/user/gardening_bot,/m/08430h,/common/topic/image,/m/02cs147,en\n1172002568007,/user/mwcl_chefmoz,1283588560000,/user/delete_bot,/m/01z4c1z,/type/object/name,La Casa Rosa Mexican Restaurant,en\n```\n\nFreebase/Wikidata Mappings\n--------------------------\n\n|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------|----------|\n| The data has been created based on the Wikidata-Dump of October 28, 2013, and contains only those links that have at least two common Wikipedia-Links and not a single disagreeing Wikipedia-Link.
