Data Requirements Library

This Data Requirements Library documents the terminology and categories used to classify and describe Environment Agency (EA) assets. It also documents the specific data attributes that are used to describe the properties of each Asset Type and its Element Types.

Asset Categories

The EA has identified different types of Asset. These Asset Types are grouped into Asset Category groupings, as listed below.

The Asset Complex Category is a special case because its Assets are used to define geospatial areas, not physical assets. Similarly, the Information Deliverables Category defines document types and attributes to be used in filenames.

You can explore each Asset Type further by clicking on its name. This will take you to a more detailed description which may be supported by photos and diagrams that highlight key elements. There is also a table which lists the Element Types and specific data attributes that are used to describe that Asset Type.

Data about each Asset Type, Element Type and their attributes can also be accessed in JSON or CSV. These formats can be directly queried by remote applications to support supplier-side automation.

Please read the Data Requirements Library in conjunction with the Environment Agency Employers Information Requirements.

The View History link at the top of the page gives you access older versions of the DRL content. Further details about these versions can be found on the Data Services Platform Forum.
