Persistent globally unique identifiers

FinBIF uses a persistent HTTP URI-identifier for all objects, as recommended by W3C (World Wide Web Consortium): Best Practices for Publishing Linked Data. You can also read about Linked Open Data.

Occurrences, taxa, collection metadata, information systems etc are given a HTTP URI-identifier that is not supposed to change. The address provides information about the object in human and machine readable formats (Accept header aware).

Most objects have been defined in FinBIF's own default namespace For example the identifier for Odonata (taxon) is There are however several other namespaces in use, for example for collection specimens of the Finnish Natural History Museum and for Univerity of Oulu.

Using full URI-identifiers can be challenging in REST-API, so instead of a full URI-identifier it is possible to use a shorter QName. For example instead of : request can be made more reliably using a short QName:

The following is a list of namespaces and their Qname prefixes known by FinBIF:

 rdf rdfs xsd xml owl vcard dc dcmitype dwc dwctype dwciri so cc skos herbo luomus utu zmuo gbif-dataset rdfschema geo"

As a further example, if the URI-identifier is then the Qname is "utu:TBR.119974" and the property dwc:vernacularName is short for

Most resources of are defined in the default namespace, and the QName prefix is an empty string "". For example if the URI-identifier is then the QName is "MX.1".

The default namespace has been divided into internal namespaces (for example "MX" for taxa, "HR" for collection metadata, etc). This information should not be used to guide any application logic. The identifiers should not be assumed to contain any information.


In ontologies there is a vocabulary that defines a schema for resources. Our schema is documented in address
