Create Categories from Legacy Topic Sets
You can use the CategoryImportFromTopic action to import categories from existing legacy topic sets. IDOL server creates one category per topic set. When you import a topic set, you can specify whether you want to maintain the original Boolean rules of the topic or import the topic as an Autonomy concept matching agent.
All categories that you import from legacy topic sets are child categories of the root category. You can move them to create a hierarchical structure. For example:
http://IDOLhost:port/action=CategoryImportFromTopic&Topic=MyTopicFile.otl&BuildNow=true
In this example, IDOL server imports the topic sets that are stored in the MyTopicFile.otl to categories in the root category. The BuildNow parameter instructs IDOL server to build the categories immediately, so they become active. You can also activate the category at a later point using the CategoryBuild action.
