SharePoint Taxonomies - Committing large amount of data to the MMD service
Once again about the SharePoint 2010 taxonomy service.
As I wrote in my previous posts, loading data into MMD service automatically can be quite a challenge. First, you must remember about illegal characters in terms labels. Second, you must trace duplicates across sibling nodes in taxonomy trees. And this could not be the end of your problems especially if you plan to load some more data at one time.
