Hoja de ruta para nodos y puertas de entrada a la información (RING) para la investigación agraria para el desarrollo


One of the most important criteria against which the RING indexes information services is the standards with which they are compliant.

The standards considered so far refer to:

  • metadata set: description vocabularies (Dublin Core, Darwin Core, Agris AP, Ag-Event AP, FoaF...)
  • knowledge organization system (KOS) / indexing scheme: controlled vocabularies and encoding schemes (classifications, thesauri, authority files, subject headings, controlled lists, taxonomies...)
  • format / syntax / notation: XML, RDF N3, CSV... 
  • architecture / technology: OAI-PMH, RSS, SRW/SRU, SOAP, XML-RPC...

Metadata sets and KOS

As far as metadata sets and subject vocabularies / knowledge organization systems (KOS) are concerned, the standards that are covered by the RING are harvested directly from the registries of the Agricultural Information Management Standards (AIMS) website. If you notice that a relevant metadata set or subject vocabulary is not present, please send some information about it to the AIMS managers and request that it be added to the AIMS registries.

Technologies and formats 

The lists of terms indicating technologies and formats are made of free tags selected by the users who submitted the services.
An initial set of keywords was provided and users have been invited to exploit the auto-complete functionality in order to use existing terms whenever possible and avoid duplicates.
These lists will be perodically revised and similar terms will be merged.
