    13 With the addition of the XLink processing, fragment harvesting, subtemplate (= fragment with an id in the Metadata table of the !GeoNetwork database) support and tools for managing directories of subtemplates, !GeoNetwork can now begin to support reusable fragments of metadata linked into records. However many sites have metadata records with common fragments of metadata that they would like to extract into directories of subtemplates. This proposal adds a batch operation for admin users that will extract fragments from a selected set of records. Subtemplates are identified as follows: if the root element of the subtemplate has a uuid attribute, then this will be the uuid of the extracted subtemplate. If there is no uuid attribute on the root element of the subtemplate, then one is obtained by calculating the checksum of its text content.

    31 This extract subtemplates function works as follows:
     31This function works as follows:

    3333 * Identify fragments of metadata that they would like to manage as reusable subtemplates. This can be done using an XPath. eg. the XPath /grg:RE_Register/grg:containedItem/gnreg:RE_RegisterItem identifies register items in an ISO19135 register record such as that describing the ANZLIC Geographic Extent Names vocabulary and shown in the following example:
    … …  
    7979}}}
    8080
    81  * Identify a field or fields within the fragment that will be used as the title of the subtemplate. It is important to choose a set of fields that will allow a human to identify the subtemplate when they choose to either reuse the subtemplate in a new record or edit in the subtemplate directories interface.
    82  * Write a small XSLT that when applied to the subtemplate, will extract the title information. As an example, here is an XSLT that when applied to an ISO19135 register item (gnreg:RE_RegisterItem), will extract the name of the register item (grg:name/gco:CharacterString) for use as the title of the subtemplate.

    104  * Choose 'Extract templates' from the 'Actions on selected set' drop down menu at the top right of the search interface.
    105  * Enter the XPath of the fragment, server side path name of the XSLT to extract a title for the subtemplate to be created from the fragment and a category to which the created subtemplates will be assigned. See the following example:
