AnnoCultor allows having a list of regular expressions and include a record only if its identifier matches one of them.

File with filters

First we need a file with regular expressions, let us call it filter.txt to select all URLs from the AnnoCultor Time Ontology that match the 19-th and 20-th century (well, it may not do exactly that, but it illustrates how a regular expressions can be set):

^http\://www\.annocultor\.eu/time/19(\d\d)$
^http\://www\.annocultor\.eu/time/20(.*)$

Selector on object rule

In the handler on precondition we tell AnnoCultor to filter certain records out: 

<ac:ObjectRule rdf:about="subjectRule">
   <ac:recordSeparator></ac:recordSeparator>
   <ac:recordIdentifier>id</ac:recordIdentifier>
   <ac:recordInformalIdentifier>label</ac:recordInformalIdentifier>
   <ac:listeners rdf:parseType="Collection"> 
      <ac:OnPreCondition>
         <ac:java><![CDATA[
           // get id
           String id = sourceDataObject.getFirstValue(new Path("id")).getValue();
           return shouldConvert(id);
         ]]> </ac:java>
      </ac:OnPreCondition>                  
   </ac:listeners>
...

Filter code

Let us write the filter itself. 

...
        </ac:propertyRules>
    </ac:ObjectRule>
</ac:objectRules>
<ac:listeners rdf:parseType="Collection">
   <ac:Declarations>
      <ac:java><![CDATA[
          List<String> patternsToConvert = new ArrayList<String>();
          List<String> log = new ArrayList<String>();
                    
          public boolean shouldConvert(String url) { 

            for (String pattern : patternsToConvert) {
               if (!pattern() && !url.isEmpty() && url.matches(pattern)) {
                  // let us create a log of records that went through
                  log.add(url);
                  return true;
               }
            }  
            
            return false;
          }    
     ]]></ac:java>
   </ac:Declarations>
   <ac:OnConversionStarts>
      <ac:java>
          patternsToConvert = FileUtils.readLines(new File("filter.txt"), "UTF-8");
      </ac:java>
   </ac:OnConversionStarts>
   <ac:OnConversionEnds>
      <ac:java><![CDATA[
          // save log
          FileUtils.writeLines(new File("includedRecords.log"), log, "UTF-8");
      ]]></ac:java>
   </ac:OnConversionEnds>
</ac:listeners>  

<ac:maxRecordsToConvert>-1</ac:maxRecordsToConvert>
</ac:Repository>
</ac:repositories>
</ac:Profile>
</rdf:RDF>

That's it.
