IGSN Registration Metadata Version 1.0

IGSN Registration Metadata Elements

IGSN e.V. and Datacite have entered a strategic partnership. The IGSN e.V. works with DataCite to provide a globally recognised persistent identifier for sample identification and tracking that facilitates the efficient sharing of samples and their associated metadata among researchers, institutions, and databases. The registration of IGSNs is now through DataCite services.

The documentation below is no longer relevant.

Version 1.0 of 2012-07-11

Element	Definition
sampleNumber	The IGSN that identifies the registered object.
registrant	The allocating agent registering the object.
relatedResourceIdentifier	The identifiers of other objects (literature, data, samples) related to this object. This element will become obsolete with the introduction of the IGSN Descriptive Metadata Schema.
log	Date and Time relevant to events concerning the registered object and its metadata.

IGSN Metadata Properties

IGSN Core Descriptive Metadata

To facilitate the discovery of samples through centralised catalogues, IGSN e.V., together with the NSF funded iSamples initiative, hosted a workshop in Los Angeles, California, on 14/15 September 2015 to draft a metadata kernel for descripitve and discovery metadata. The IGSN kernel metadata schema can be found at http://schema.igsn.org

IGSN -> Dublin Core Cross-walk

The Mapping of IGSN Descriptive Metadata elements to Dublin Core elements should be used to serve Dublin Core metadata through the OAI-PMH service for harvesting by generic clients, e.g. Geonetwork Open Source.
