Rules and guidelines for intelligent structure models

Rules and guidelines for intelligent structure models

Consider the following rules and guidelines when you work with intelligent structure models:
  • If the
    intelligent structure model
    does not match the input file or only partially matches the input file, there might be a large amount of unidentified data.
  • Before you run a mapping with a Hadoop Files source, verify that you configured the field mapping correctly. The source fields and the Structure Parser transformation incoming fields have the same names, so you can automatically map the fields. For configuration information, see Processing input from a Hadoop Files source.
  • Before you run a mapping with a flat file source, verify that the Source transformation uses a reference file that contains a list of paths to the files that you want the Structure Parser transformation to process. When you configure the Source transformation, do not select the file itself that you want to process. Ensure that the Source transformation has one source field. Ensure that the Structure Parser transformation accesses the source field on the
    Field Mapping
    tab. For configuration information, see Processing input from a flat file source.
  • An intelligent structure model can parse the data within PDF form fields but not data outside the fields.
  • An intelligent structure model can parse data within Microsoft Word tables. All other data is collected as unparsed nodes.
  • ORC files can only be read through a flat file connection in
    Data Integration
    . ORC does not support streaming.
