The INSPIRE Implementing Rules for Metadata specify the metadata elements that are relevant for INSPIRE. To understand the role of metadata within INSPIRE it is important to figure out the different aspects of metadata elements. This leads to a clear separation of concerns and helps to identify reasonable INSPIRE metadata elements.
In accordance with the INSPIRE Directive, three different types or levels of metadata are distinguished: metadata for discovery, metadata for evaluation, and metadata for use. The following figure shows the relation between these different types.
Metadata for Discovery
Elements of this category satisfy the need to search for resources. The metadata element provide information to convey to the inquirer the nature and content of the data resources. It answers "what, why, when, who, where and how" questions about spatial resources.
This type of metadata plays a major role in the context on catalouges services where users formulate queries to search for metadata records describing one or more resources. In the context of catalogue service, these elements are often called queryables or search attributes.
Thus, the INSPIRE Metadata elements described by the INSPIRE Implementing Rules for Metadata fall entirely into this section. Examples are:
- Resource title
- Resource abstract
- Lineage
Metadata for Evaluation
Elements of this category are needed to assess if the resource described by the metadata fits to the requirements of the user or the given use case. The user has identified a candidate resource, potentially as a result of the discovery activity and the user wants to determine whether this resource satisfies the user’s requirements or not.
In the context of catalouge services, these elements are comparable to Returnable properties or Response metadata. Response metadata can be used for evaluation and to answer questions like:
- What data and/or service are available within an area of interest?
- Who is responsible for the resource and the associated metadata?
- Who can I contact to get access, use and pricing of the resource?
- Does the identified resource contain sufficient information to enable a sensible analysis to be made for my purposes?
- What is the quality of the identified resource?
- How and where can I obtain the resource?
This category is partially covered by the INSPIRE Metadata elements. Examples are:
- Spatial resolution
- Resource responsible party
- Conditions applying for access and use
Metadata for Use
Elements of this category come into play after a user has chosen a specific resource. The resource is accessible and can be used. Specific metadata elements will support the user in fully understanding the data and using it properly resulting in more reliable analysis and more confidence in the results.
Elements of this category are out of scope of the INSPIRE Implementing Rules for Metadata. Instead, they are covered by the INSPIRE Data Specifications of the Annex themes I,II and II accordingly (see Metadata for evaluation and use)
