== What is Record Filter ==
+
 
+
Record may contains many attributes and annotations that really does not required for. For increase productivity, decrease information sent (by SCA), stored in JMS queue etc, its possible to create a copy of Record with only attributes/annotations passed through some filter and to work with this small copy of Record. Record Filter is a helper class that implements this filtering.
+
 
+
Now Record Filter is a part of Blackboard functionality. Its possible to get filtered Record from Blackboard.
+
 
+
== Configuration ==
+
 
+
By default, Blackboard uses record filter configuration file RecordFilters.xml
+
 
+
Schema: RecordFilters.xsd, see attachment.
+
 
+
There are series of filters (tag Filter)
+
Record filter will search first appropriate Filter by name specified. If there is no filter found, RecordFilterNotFoundException will be thrown. Attribute/Annotation will be copied if correspondent, by name, Attribute/Annotation tag will be found in Filter. Attribute "keepAnnotations" is a flag to copy internal attribute annotations.
+
 
+
== Example ==
+
 
+
<source lang="xml">
+
<RecordFilters>
+
  <Filter name="only-attributes">
+
    <Attribute name="*"/>
+
  </Filter>
+
  <Filter name="no-filter">
+
    <Attribute name="*" keepAnnotations="true"/>
+
    <Annotation name="*"/>
+
  </Filter>
+
  <Filter name="nothing"/>
+
  <Filter name="only-attribute1">
+
    <Attribute name="attribute1"/>
+
  </Filter>
+
  <Filter name="filter-single-and-datetime">
+
    <Attribute name="single value"/>
+
    <Attribute name="datetime value"/>
+
  </Filter>
+
</RecordFilters>
+
</source>
