== Overview ==

This proposal extends the GeoNetwork search interface to allow search metadata using INSPIRE criteria. The proposal is based on NGR project, that extended the Search GUI to allow search of INSPIRE compliant metadata.

== Motivations ==
Extend the current search gui to support the search of metadata using INSPIRE criteria.

== Proposal == 

=== Configure the avalability of INSPIRE options ===

The search for INSPIRE metadata panel is not visible by default. A mechanism is added in order to turn on/off INSPIRE search panel in config-gui.xml.

{{{
<config>
  <!--
    INSPIRE integration:
    Set this parameter to "1" to enable INSPIRE, showing INSPIRE panel in advanced searcher.
   -->
  <inspire>0</inspire>
</config>
}}}

This parameter can be used to enable/disable the avalability of INSPIRE in GeoNetwork, maybe also for [wiki:InspireView] 

=== Search panel ===

If INSPIRE is enabled, the INSPIRE search options are shown in the advanced search panel:

The search panel for INSPIRE allows searching with this criteria fields:

 * Only INSPIRE metadata: Searches metadata associated with category=Inspire. This category should be added to Categories table.

 * Title (Metadata title)

 * INSPIRE Annex (See [http://inspire.jrc.ec.europa.eu/reports/ImplementingRules/inspireDataspecD2_3v2.0.pdf]) 

 * INSPIRE Theme (See [http://inspire.jrc.ec.europa.eu/reports/ImplementingRules/inspireDataspecD2_3v2.0.pdf])

 * Source type (Hierarchy level)

 * Service type (Online protocol)

 * Organisation (Group): '''To Check'''

=== Indexing ===

||'''Search field'''||'''Lucene field'''||
||Title (Metadata title)||title||
||Inspire annex||inspireannex ('''new''')||
||INSPIRE theme||inspiretheme ('''new''')||
||Source type (Hierarchy level)||type||
||Service type (Online protocol)||protocol||
||Organization (Group)||group||

Two new fields should be added to the indexing of iso19139 metadata to allow search for INSPIRE annex and INSPIRE theme fields (index-fields.xsl):
