Adding fields to an existing Extract step
Foroptimizationpurposes,itisbettertoaddfieldstoanexistingExtractstepthantohaveasuccession
ofextractionsteps.
ToaddfieldstoanexistingExtractstep:
1. IntheDataViewerpane,selectthedatathatneedstobeextracted.(See"Selectingdata"onthe
nextpage.)
2. SelectanExtractstepontheStepspane.
3. Right-clickonthedataandselectAdd Extract Field,ordrag&dropthedataontheDataModel.
WhendataaredroppedontheDataModel,theyarebydefaultaddedtothecurrentlyselectedExtract
step.
Extracting metadata
ThepagesinPDF/VTfilescanbegroupedonseverallevels.Additionalinformation,suchasTLEs-a
TLEisaTaggedLogicalElement-inAFPfiles,canbeattachedtoeachlevelinthestructure.Thestruc-
tureandadditionalinformationarestoredinthefile'smetadata.
Whensettingupadatamappingconfigurationforthesetypeoffiles,ametadatalevelcanbesetto
definearecord.
Next,ifyouareusingthewizard,youcanselectfieldstobeextractedfromthemetadataautomatically.
Itisalsopossibletoextractinformationfromthemetadatawithoutthewizard.Here'showtodothat.
1. GototheStepspane.
2. ClicktheExtract steptoolbarbutton.ThisaddsanExtractstepwithonefield.Alternativelyyou
couldselectanexistingExtractstepandaddafieldtoit.
3. OntheExtract step propertiespane,underField definition,setthefield'sModetoMetadata.
4. SelecttheLevelofthemetadataonwhichtheinformationcanbefound.
5. SelectthePropertytoextract.
AlternativelyyoucouldcreateaJavaScriptextraction(see"UsingscriptsintheDataMapper"on
page362and"extractMeta()"onpage384).

l
Changethenamesoffieldsthatareincludedintheextraction.
l
Changetheorderinwhichfieldsareextracted.
