A Series is analogous to a MEDIN Series which can be defined as a collection of datasets and reports collected in relation to a survey or data collection campaign, linked by a common research question. Series must be described by a metadata record. A Series must contain one or more reports and / or datasets.

A Dataset is defined as a 'pillar' of data and information related to a single parameter, instrument or method. Datasets must be described by a metadata record. A Series can contain one or more datasets.

A Report is defined as a set of documents relating to part, or the whole of a survey or data collection campaign. Reports must be described by a metadata record. A Series can contain one or more reports.

The Crown Estate's requirements for metadata are:

Series - MEDIN Discovery Standard (series metadata)

Dataset - MEDIN Discovery Standard (dataset metadata)

Report - The Crown Estate Report Metadata

The spatial reference system of data should be fully defined.

Where appropriate data should conform to the MEDIN Data Guidelines

MEDIN provide free workshops to help users understand MEDIN metadata and data guidelines. We recommend that you sign up to one of these workshops should you be working with marine data.
