ISEAL Core Metadata Set Specification

This page provides a reference specification for the ISEAL Core Metadata set (ISEAL Core).

ISEAL Core is a set of structured terms and vocabularies that can be used as metadata to describe, share, and reuse different digital resources across the ISEAL Community and broader set of stakeholders. The resources described using the ISEAL Core are those that sustainability systems typically collect, curate, manage, use, publish and archive. They may be datasets, published research, certificates, videos, images, maps, or other organizational documentation.

Clusters and Modules

Metadata elements in ISEAL Core are organized around three clusters and ten modules.

Global Certification Impact
Coverage Assurance Evaluation
Form Certificate
Provenance Certificate Holder, Owner or Certified organization
Scope Certified Resource or Site

Metadata Elements

ISEAL Core uses elements from the following standard metadata schemas:

  • Dublin Core Elements with the dc namespace prefix. These were originally designated in 1995 and are considered deprecated and superseded by Dublin Core Terms. Due to legacy code in the DSpace software we must still use some of these.
  • Dublin Core Terms with the dcterms namespace prefix. These contain the original Dublin Core Terms and add others. As of 2008 these supercede the original Dublin Core Elements.

General guidelines for metadata using ISEAL Core:

  • Encoding: metadata should be encoded in UTF-8 to ensure correct representation of international characters.
  • Applicability: metadata should describe what the item is, not what it isn't. If a metadata element is not applicable you should not use it. Do not enter "N/A"!
