Vocabularies
A list of authoritative vocabularies and documentation/papers relevant to publishing MELODIES datasets.
http://www.w3.org/TR/vocab-dcat/
This provides the framework for describing high-level information about any kind of dataset. It should not go into much domain-specific detail. The main user of such metadata is a search engine which wants to index datasets.
https://joinup.ec.europa.eu/node/139283/
Defines structures which are left open in DCAT itself, e.g. how to specify a bounding box or temporal extent. Very relevant!

SSN may be used as a framework for the actual data, but some parts of it can also be useful for Dataset metadata. For example, search engines may want to index what is measured/calculated in a dataset, like "air temperate". For that, ssn:observedProperty could be used and attached to the dataset. Note that this is new territory and probably hasn't been done before in that way.

It "is based on DCAT that it extends with a number of additional properties and classes suitable for expressing the quality of a dataset."
