You play around with a technology for 13 years and it still surprises you…
This issue cropped up today with a client’s installation of SharePoint 2010 Server Enterprise Edition.
A wiki site was created for capturing and sharing knowledge within a tech support team. A key requirement was the ability to quickly search for information and then refine by tags, e.g. to locate the relevant manual or warranty status.
Within the site, for the wiki pages, we pointed the wiki ‘Categories’ column to a new keywords term set – ‘Tech Support Tags’. so that only relevant tags would be suggested. The term set has been configured so that anyone can add terms. In addition, a document library was created to store the manuals, deployment guides etc. We added a Managed Metadata column called ‘Categories’ and also pointed it at the Tech Support Tags term set. So results would be displayed for knowledge pages and formal documents, all tagged using the same term set. To complete the solution, a search box was added to the site home page configured to only return results from within the site. Along with a modified results page to adjust the presentation of search results, but the details are not relevant for this post.
Users were able to tag documents but the Categories column appeared empty in the document library view.
We had to set permissions for the hidden taxonomy list in the site collection.
To do so, add the following to the end of the site collection URL – /lists/taxonomyhiddenlist
Then, within the list that is displayed (you should see the current set of tags listed), set permissions so that people are able to access it. The values will then be visible in the appropriate columns within the document library.
