Paperity Central: An Open Catalog of All Scholarly Literature

The goal of this project is to build Paperity Central, a global universal catalog of Open Access (OA) literature "gold" and "green" combined that will ultimately include 100% of past and new open literature, and subsequently with the advent of universal OA will become a catalog of all scholarly literature published anywhere in the world. Paperity Central will combine automatic indexing of journals and repositories, with manual data curation via a "wiki"-type functionality; will expose open APIs for programmatic access to data and development of add-on services and applications; and will greatly facilitate the discovery and navigation in OA literature, as well as dissemination of new research. The catalog will be built by extending an existing prototype, Paperity an aggregator of gold & hybrid OA journals with three key features: 1) The aggregation of green OA literature from repositories. "Green" metadata will be seamlessly merged with "gold", in a systematic and consistent way: with deduplication of repeated entries, assignment of globally unique permanent identifiers, reconnecting every item with its primary source of origin (e.g., a journal) and establishing semantic links with related objects: author profiles, institutions, funders, grants, datasets, protocols, reviews, cited/citing works... ‡,§ | © Wojnarski M, Hanken Kurtz D.

Manual curation will be particularly important for "green" metadata, which frequently contain missing or incorrect information; and for cataloguing those publications that are inaccessible for automatic harvesting, like the articles posted on author homepages only. 3) Open APIs, featuring in particular a feedback loop from Paperity to repositories (including DSpace, a partner in this proposal), enabling source repositories to pull all metadata corrections and extensions collected by Paperity.
