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 InspireView

Search panel

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

Some changes proposed to add also:

• Made INSPIRE collapsible and hidden by default
• Add "Either of the words" as first search parameter and put "Exact phrase", "All of the words" and "Without the words" in a collapsible panel, hidden by default.
• Show INSPIRE terms without using an scrollbar

Additions:

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):

<xsl:for-each select="gmd:keyword/gco:CharacterString|gmd:keyword/gmd:PT_FreeText/gmd:textGroup/gmd:LocalisedCharacterString">
  <xsl:variable name="keywordLower" select="translate(string(.),$upper,$lower)"/>
  <Field name="keyword" string="{string(.)}" store="true" index="true" token="false"/>
  <Field name="subject" string="{string(.)}" store="true" index="true" token="false"/>

  <xsl:if test="string-length(.) &gt; 0">
    <xsl:if test="$keywordLower='coordinate reference systems' or $keywordLower='geographical grid systems'
