Because of a specific requirement, I'm developing a functionality for our
application that consists of a metadata searching module. This module
extents the Simple CSW Client (eXcat) to enrich its provided results
through Geonetwork's XML services and with additional geographicinformation
from our databases.
For example, I've been able to update the XSL eXcat template to include
options to export metadata in ZIP (MEF FORMAT) and XML (iso19139), in the
same way that it's possible from the Geonetwork.
I would like to include athumbnails visualization, so I would have to
recover the ID (Metadata internal identifier) in Geonetwork database and the
thumbnail's file name in metadatum in order to compose the Geonetwork's
respective request to get a thumbnail as follows:
After looking around Geonetwork available XML services, Search metadata
(xml.search) is the only service that includes the ID (Metadata internal
identifier) into its response and no other service includes in its response
any kind of thumbnail information.
My questions are:
1) Is there another way (service) to obtain the ID (Metadata internal
identifier) from the UUID (Metadata Universally Unique Identifier) for a
single metadatum, for example a kind of Search metadata xml.search service
that receives as parameter the UUID and returns as a response the metadatum
record with its additional geonet:info section.
2) Is there a way (service) to know if the metadata have a thumbnail, or
the only way to know that is getting the metadata and look if exists a file
name or not in the thumbnail sections?
3) If the answer to my first question was no, developing a service that
includes in its response the metadutum ID wich receives as parameter the
UUID, will it be a useful feature to be incorporated into Geonetwork
Thanks in advance for your time, I hope to have been enough clear with my
