OpenCitations Meta RDF dataset of all bibliographic metadata and its provenance information

This dataset contains all the bibliographic metadata and its provernance information (in JSON-LD format) included in OpenCitations Meta.The data and the provenance are organized through a complex structure of folders and subfolders, that allows you to quickly find any entity from its URI. The first level consists of the following folders, that are provided compressed and separately:<br><b>[folder "ar"]</b>: contains the data and provenance of the responsible agent type entities (http://purl.org/spar/pro/RoleInTime);<b>[folder "br"]</b>: contains the data and provenance of the entities of type bibliographic resource (http:///purl.org/spar/fabio/Expression);<b>[folder "id"]</b>: contains the data and provenance of the identifier entities (http://purl.org/spar/datacite/Identifier);<b>[folder "ra"]</b>: contains the data and provenance of the responsible agent type entities (http://xmlns.com/foaf/0.1/Agent);<b>[folder "ra"]</b>: contains the data and provenance of resource embodiment entities (http://purl.org/spar/fabio/Manifestation).The inner folders are named through the <b>supplier prefix</b> of the contained entities. It is a prefix that allows you to recognize the entity membership index (e.g., OpenCitations Meta corresponds to <b>06*0</b>).After that, the folders have <b>numeric names</b>, which refer to the range of contained entities. For example, the 10000 folder contains entities from 1 to 10000. Inside, you can find the <b>zipped </b>RDF data.At the same level, additional folders containing the <b>provenance </b>are named with the same criteria already seen. Then, the 1000 folder includes the provenance of the entities from 1 to 1000. The provenance is located inside a folder called <b>prov</b>, also in zipped JSON-LD format.For example, data related to the entity is located in the folder /br/06250/10000/1000/1000.zip, while information about provenance in /br/06250/10000/1000/prov/1000.zipThis version of the dataset contains:114,621,237 bibliographic entities298,847,794 authors and 2,465,711 editors (counted by their roles, without disambiguating individual711,711 publication venues241,783 publishersThe compressed archives total 29GB, using the lzma2 compression algorithm, and expand to 43GB when decompressed. The JSON-LD files are further compressed using the same lzma2 algorithm. It is recommended to process these files as compressed without extracting them, to manage data more efficiently.Additional information about OpenCitations Meta at the official webpage.<br>
