[GeoNetwork-devel] fgdc metadata identifier in CSW response

Hi all, testing OpenLayers CSW format I'm facing an issue on FGDC demo
data we have after setup.
It looks like FGDC extract-uuid always return an empty UUID.

I would suggest to add the following to CSW output mapping in order to
always have a UUID in CSW response.

Index: web/geonetwork/xml/csw/schemas/fgdc-std/ogc-*.xsl
- <xsl:for-each select="idinfo/citation/citeinfo/title/@cat_id">
- <dc:identifier><xsl:value-of select="."/></dc:identifier>
- </xsl:for-each>
-
+ <xsl:choose>
+ <xsl:when test="idinfo/citation/citeinfo/title/@cat_id">
+ <xsl:for-each select="idinfo/citation/citeinfo/title/@cat_id">
+ <dc:identifier><xsl:value-of select="."/></dc:identifier>
+ </xsl:for-each>
+ </xsl:when>
+ <xsl:otherwise>
+ <dc:identifier><xsl:value-of select="geonet:info/uuid"/></dc:identifier>
+ </xsl:otherwise>
+ </xsl:choose>

Does this sounds good to FGDC users ?
Thanks.

Yes, it does. The use of the cat_id attribute is an unofficial
extension of the FGDC schema/DTD, but widely (although not universally)
used within the FGDC community to hold a unique catalog identifier.

If I read the code correctly, this is used in generating the CSW
response and creates a new identifier if there is not one present in the
FGDC record. That's the right way for it to work.

I haven't had a chance to look at the relevant record ingest code, but
is there also something equivalent in there? That is, to parse the
identifier from cat_id if it's present, and to generate a new identifier
if it's not? That might be useful for internal purposes.
