If you make any changes to the object structure, keep the following in mind.
If you want the new fields or objects to appear on the EDM, make sure to add them to the first section of the Enterprise Data Manager file and to any of the page definitions later in the file (this includes search pages).
If the new fields require normalization, parsing, or phonetic encoding, define the new structures in the Match Field file.
If a new field will be used for matching, add it to the blocking query used for match processing as well as to the match string in the Match Field file.
If the new fields or objects will be included in incoming messages, add them to the inbound OTD structure (the outbound OTD will be updated when you regenerate the application).
