This page describes the changes made to JHove2 to get the modules running.

Modifications to existing config files

/config/spring/jhove2-framework-config.xml

Add the following section to the xml. This adds a developer BnF to Jhove2.

jhove2-framework-config.xml
	<!-- BnF (Bibliothéque nationale de France) agent bean -->
	<bean id="BnFAgent" class="org.jhove2.core.Agent" scope="singleton">
		<constructor-arg value="Bibliothèque nationale de France"
		                 type="java.lang.String"/>
		<constructor-arg value="Corporate"
		                 type="org.jhove2.core.Agent$Type"/>
		<property name="URI" value="http://www.bnf.fr/"/>
	</bean>

/config/spring/persist/jhove2-persist-config.xml

Must be set to BerkeleyDB persistence because of several bugs in the InMemory persistence.

You must also change the envHome property in the BerkeleyDbPersistenceManager bean. This path must be valid and readable!

jhove2-persist-config.xml
	<bean id="BerkeleyDbPersistenceManager" class="org.jhove2.persist.berkeleydpl.BerkeleyDbPersistenceManager"
	     scope="singleton">
	     <!--property name="envHome" value="C:\"/-->
	     <property name="envHome" value="C:\Java\BerkeleyDb\"/>
	     <!--property name="envHome" value="/tmp/BerkeleyDb/"/-->
 	     <property name="entityStoreName" value="JHOVE2_Entity_Store"/>
 	     <property name="storeConfig" ref="StoreConfig"/>
	     <property name="envConfig" ref="EnvironmentConfig"/>
	</bean>

/config/droid/DROID_SignatureFile_V20.xml

The Droid signature file needs to be modified to recognize ARC and WARC files correctly.

Insert the follow section in the internal signature part.

DROID_SignatureFile_V20.xml
        <!-- ARC, matches "filedesc:" in beginning of file. -->
        <InternalSignature ID="123456" Specificity="Specific">
            <ByteSequence Reference="BOFoffset">
                <SubSequence Position="1" SubSeqMinOffset="0" SubSeqMaxOffset="0" MinFragLength="0">
                    <Sequence>66696C65646573633A</Sequence>

                </SubSequence>
            </ByteSequence>
        </InternalSignature>
        <!-- WARC, matches "WARC/" in beginning of file. -->
        <InternalSignature ID="12345" Specificity="Specific">
            <ByteSequence Reference="BOFoffset">
                <SubSequence Position="1" SubSeqMinOffset="0" SubSeqMaxOffset="0" MinFragLength="0">
                    <Sequence>574152432F</Sequence>

                </SubSequence>
            </ByteSequence>
        </InternalSignature>

Insert the follow section in the file format part.
