2.6.8 Exchanging metadata


After the metadata has been gathered and recorded, it can be published. There are three methods used for the publishing of metadata;

1. Producing new metadata in the metadata editor of a register. 2. Importing existing metadata as XML. 3. Reading existing metadata about the capabilities of a service.


The first two methods are based on entering metadata directly into a register. There is no automated connection with the source information that recognises and carries out changes.


Metadata editor

If an organisation does not have any metadata yet, it can use the metadata editor that is included in a register. With this editor, metadata can be constructed according to the Dutch metadata standard for geography, version 1.2. It is also possible to set down metadata for services according to the Dutch metadata profile on ISO 19119 for services, version 1.1.


Importing metadata via XML

A more advanced way of including metadata in a register is to upload an XML.


Reading metadata about the capabilities of a service

Each OGC service (WMS, WFS, WCS, etc.) has a capabilities document. In this document some metadata elements of the service are included automatically when the service is produced. This method focuses on using the metadata information from the capabilities document. This is of predominate importance for organisations who want to publish a restricted number of services (an OGC catalogue service quickly becomes an overly heavy solution, considering the number of services published). This is an easy way to publish metadata. Using the capabilities file offers the possibility of reading metadata from the service itself and referencing it to the metadata XML of the data that will be provided; however not all the mandatory metadata elements of the Dutch profile on ISO 19119 can be stored here.

In a register the capabilities file can be read and transferred to ISO19119/CSW 2.0.2 ISO AP. This metadata can be completed further with the support of the editor.
