This set of standards, with the exception of Dublin Core and DCAT, is also built on the domain reference model of ISO 19101-1, but, in contrast to the data model standards, which are focused on individual features and their characteristics, these standards are focused on the description of data sets containing information about one or, typically, many feature instances.

ISO 15836:2009 establishes a standard for cross-domain resource description, known as the Dublin Core Metadata Element Set. Like RFC 3986, this International Standard does not limit what might be a resource.
+
These standards describe metadata:
−
ISO 15836:2009 defines the elements typically used in the context of an application profile, which constrains or specifies their use in accordance with local or community-based requirements and policies. However, it does not define implementation detail, which is outside the scope of ISO 15836:2009.

Because ISO 15836 is so popular, it is probably useful for providing high-level metadata of the likes of a dataset series (e.g. a national medium scale mapping series), so that it can be documented with other resources within the organisation. However, because it uses free text and is at a high level, it is difficult to use effectively any such metadata describing an individual geo-spatial dataset, never mind describing individual features within the dataset.

Metadata standards

This set of standards, with the exception of Dublin Core and DCAT, is also built on the domain reference model of ISO 19101-1, but, in contrast to the data model standards, which are focused on individual features and their characteristics, these standards are focused on the description of data sets containing information about one or, typically, many feature instances.

These standards describe metadata:

  • ISO 15836:2009, Information and documentation -- The Dublin Core metadata element set


The table provides a more comprehensive list of standards related to metadata.
