Catalogs / repositories

If you want to identify the most suitable published semantic structures for your agri-food data, the best places to go are specialized catalogs or repositories that are dedicated to the agri-food domain. But also general catalogs searchable by domain can be of help.

An important difference to be made is the one between catalogs / directories / registries on the one hand and repositories on the other: registries are conceived as metadata catalogs, providing descriptions and categorization of vocabularies and linking to the original website and original serialization of the standard, while repositories host the full content of the vocabulary, so that the terms themselves can be browsed.

Below is an overview of some existing catalogs / repositories of data standards and vocabularies.

1. Domain specific

General

  • FAIRsharing
    https://fairsharing.org/
    Evolved from the Biosharing directory of standards for life sciences, it is now a general directory of data standards of different types. It has a good tagging system but the coverage of agri-food standards is still poor.

  • Linked Open Vocabularies (LOV)
    https://lov.okfn.org/dataset/lov  
    Directory of RDF vocabularies (see lesson 4.3 for a description of RDF) spanning across all disciplines. It is not organized by domain or discipline and vocabularies can only be browsed through a small number of free tags.      

  • The Basel Register of Thesauri, Ontologies & Classifications (BARTOC)
    http://bartoc.org/     
    BARTOC includes all types of KOS in any format, across all subject areas. The categorization of vocabularies is quite generic (food and agriculture would fall partly under Pure Science and partly under Technology without further sub-categorizations).
