IDENA: Metadata details
One of the main objectives of a Spatial Data Infrastructure is to make it possible to search for and consult existing spatial information. To do so, it is essential to catalogue all the spatial data and then upload it on to a metadata catalogue service. SITNA has been requesting the creation of metadata for several years.
Access to the metadata is made through the website for the Navarra Spatial Data Infrastructure, IDENA.
According to the most usual definition, metadata are "data about data". It describes data's contents, quality, condition and other characteristics. In short, it helps a person to locate and understand the spatial data available.
Spatial metadata must be thought of as a legend that identifies the producers of the data, the documentary sources used in production, the data's attributes, the publication date, reference system, maintenance frequency...
Metadata has several objectives:
IDENA metadata profile
Documentation has become a necessary job to manage and use the data correctly. This best use is not only considered for internal use within an organisation or company, but it can also be shared with other data producers and among producers and users.
Metadata standards have been created so that this documentation can be understood by everyone, or in other words, so that we are all "speaking the same language".
The aim of a metadata standard is to provide a common structure to describe geographic digital data. It defines the elements that make up the metadata, provides a single schema and establishes common terminology for everyone, user and producers.
The INSPIRE initiative imposes metadata rules. Navarra, following the proposals of the Work Group to create the IDEE (Spatial Data Infrastructure for Spain) has adopted a subset of elements that guarantee a sufficient integration with metadata from the rest of the European SDI initiatives that is called the IDENA metadata profile.
