OpenCitations provides additional tools for retrieving information about bibliographic and citation data. In particular:
Open Citation Identifier Resolution Service. OpenCitations provides a resolution service for Open Citation Identifiers (OCIs). An OCI is a globally unique persistent identifier for bibliographic citations, created and maintained by OpenCitations. The resolution service enables one to specify an OCI and returns information about that citation.
In-Text Reference Pointer Identifier Resolution Service. OpenCitations provides a resolution service for In-Text Reference Pointer Identifiers (InTRePID). An InTRePID is a globally unique persistent identifier for in-text reference pointers, created and maintained by OpenCitations. The resolution service enables one to specify an InTRePID and returns information about that specific citation.
OpenCitations created several software applications and libraries used to create all the data stored in the various databases. In particular:
BEE, a software for parsing articles from the Open Access Subset of biomedical literature hosted by Europe PubMed Central (EPMC) and encoded in JATS/XML; we have recently extended it for creating the CCC corpus, which now allows to extract also in-text references and discourse elements (e.g. sentences, paragraphs, sections)
SPACIN, a software for transforming JSON data (output of BEE) into RDF according to the OCDM; we have recently extended it for creating the CCC corpus, so as to reengineer information about in-text references and discourse elements.
Create New Citations, a software for creating citation indexes (i.e. doi-to-doi citations) according to OCDM;
BCite, a user-friendly web application - released in beta version - for creating RDF-data according to OCDM from lists of bibliographic references;
Moreover, the following tools support the development of applications leveraging data organised according to OCDM.
