The Land Portal's Land Library contains highly curated metadata of over 50,000 land-related publications, articles and multimedia from well over 1,000 information providers.

In order to combine these different databases that the Land Portal harvests metadata from, the Land Portal has consolidated certain elements from these different databases to fit one standardized metadata model in the Land Portal's Land Library.

One of the elements in metadata about resources that the Land Portal curates, is the type of resource. Many organizations and information providers use different terminologies to describe the types of resources they publish. The Land Portal has therefore created several broad categories of resource types, to be able to consolidate these various classifications.

Below you can find the list of resource types the Land Library uses, along with a short description of what is meant with each category.
