What is metadata?

Metadata is the information about the data that your publishing online. It allows users as well as computers to understand what kind of information they can expect when they dig into your publication or dataset and the context of this information.

The Open Data community has developed standard fields that should at least be included when you publish your information online. For bibliographic resources, this standard metadata schema is called the Dublin Core Metadata Model.

The Land Library follows the Dublin Core metadata model, with a few adjustments and additions to provide users even more information about the resources that exist in the Library. These adjustments and additions are of course not mandatory to follow, but we highly recommend it.

What is the Land Library's metadata model?

Below you can find the different metadata fields the Land Library's metada model contains:
