Mapping types of ATG repository

The mapping a repository is very important in a database design, because if it is not done correctly, you may not be able to set-up your repository XML correctly, and if this is not done, you'll never be able to figure out what went wrong, or why your repository is functioning properly. Let us pick up various mapping topics and learn when to use them.

XML Files Combination

    An XML file might appear at several points in the CONFIGPATH. The ATG platform, at runtime, automatically combines all the XML files in the CONFIGPATH with the same name into a single composite file, which is then used by the appropriate component.
    When two files are matched up, the way that they are combined is defined by an extra attribute that is specified in file 2 called xml-combine. This attribute is used only to specify how the files are combined, and is removed before the resulting file is generated. The xml-combine attribute can have the following values:

• xml-combine="replace"
• xml-combine="remove"
• xml-combine="append"
• xml-combine="append-without-matching"
• xml-combine="prepend"
• xml-combine="prepend-without-matching"
