I know this question gets asked a lot, and I've read the other threads, but without success. Most other people seemed to be trying to get XML metadata extraction within the web content management system. I don't know if my situation is significantly different.I would like to be able to import multiple TEI XML files in the system using Alfresco mounted as a network drive, and have them recognised as being TEI XML files, and have various bits of information extracted and put into some custom metadata fields. I have the network drive working. And I have created an aspect which defines the custom metadata fields. What I don't have working is the metadata extraction.My TEI XML files look like this:
<TEI.2 id="_jamesi_t1428_7_1_d6_trans" n="jamesi_trans">
<teiHeader>
<fileDesc>
<titleStmt>
<title>Procedure: preamble</title>
</titleStmt>
<editionStmt>
<edition n="session">jamesi_t1428_7_1_d2_trans</edition>
</editionStmt>
<publicationStmt>
<date>14280712</date>
</publicationStmt>
</fileDesc>
</teiHeader>
<text>…</text>
</TEI.2>
(no XML processing instruction or DTD and no namespaces)The model for my data looks like this:
<model name="rps:rpsModel" xmlns="http://www.alfresco.org/model/dictionary/1.0">
…
<namespaces>
<namespace uri="rps.ns" prefix="rps"/>
</namespaces>
<types>
<type name="rps:document">
<title>RPS document</title>
<parent>cm:content</parent>
<mandatory-aspects>
<aspect>cm:generalclassifiable</aspect>
</mandatory-aspects>
</type>
</types>
<aspects>
<aspect name="rps:metadata">
<title>RPS Metadata</title>
<properties>
<property name="rps:id">
<type>d:text</type>
</property>
<property name="rps:reign">
<type>d:text</type>
</property>
<property name="rps:session">
<type>d:text</type>
</property>
<property name="rps:date">
<type>d:int</type>
</property>
</properties>
</aspect>
</aspects>
</model>
With the following additions to web-client-config-custom.xml, I can add the RPS Metadata aspect to objects in Alfresco:
<alfresco-config>
<config evaluator="aspect-name" condition="rps:metadata">
<property-sheet>
<show-property name="rps:id" display-label-id="rpsID"/>
<show-property name="rps:reign" display-label-id="rpsReign"/>
<show-property name="rps:session" display-label-id="rpsSession"/>
<show-property name="rps:date" display-label-id="rpsDate"/>
</property-sheet>
</config>
<config evaluator="string-compare" condition="Content Wizards">
<content-types>
<type name="rps:document"/>
</content-types>
</config>
<config evaluator="string-compare" condition="Action Wizards">
<aspects>
<aspect name="rps:metadata"/>
</aspects>
<specialise-types>
<type name="rps:document"/>
</specialise-types>
</config>
</alfresco-config>
In wcm-xml-metadata-extracter-context.xml, I have added an entry to the bean extracter.xml.sample.selector.XPathSelector:
<entry key="/TEI.2">
<ref bean="extracter.TEIMetadataExtracter" />
</entry>
This should match the root element of my TEI XML files. Right?In custom-metadata-extrators-context.xml, I've added the following bean:
<bean id="extracter.TEIMetadataExtracter" class="org.alfresco.repo.content.metadata.xml.XPathMetadataExtracter" parent="baseMetadataExtracter" init-method="init" >
<property name="mappingProperties">
<bean class="org.springframework.beans.factory.config.PropertiesFactoryBean">
<property name="properties">
<props>
<prop key="namespace.prefix.rps">rps.ns</prop>
<prop key="rpsID">rps:id</prop>
<prop key="rpsReign">rps:reign</prop>
<prop key="rpsSession">rps:session</prop>
<prop key="rpsDate">rps:date</prop>
</props>
</property>
</bean>
</property>
<property name="xpathMappingProperties">
<bean class="org.springframework.beans.factory.config.PropertiesFactoryBean">
<property name="properties">
<props>
<!– should there be some namespace prop here? –>
<prop key="rpsID">/TEI.2/@id</prop>
<prop key="rpsReign">/TEI.2/teiHeader/fileDesc/titleStmt/title/text()</prop>
<prop key="rpsSession">/TEI.2/teiHeader/fileDesc/editionStmt/edition[@n='session']/text()</prop>
<prop key="rpsDate">/TEI.2/teiHeader/fileDesc/publicationStmt/date/text()</prop>
</props>
</property>
</bean>
</property>
</bean>
Again, these XPath strings should match elements and attributes in my TEI XML documents, right?These XML config files are getting loaded, but to no effect. The custom metadata fields are not added upon ingest, nor are they populated when I add the custom aspect to the object and run the action for extracting metadata.Do I have things in the right files? Are there other changes I should make to any of the config files? Is it a namespace issue? I made up a namespace for my custom aspect, but it isn't used in the TEI XML files I want to extract metadata from. These documents have no namespace. How does one handle that (an empty <prop> element caused an error)?Thanks.(edit: my Alfresco version is Community - v3.3.0 (2765))
