In our company we have different functionality which use some shared taxonomy terms like "Business Unit" or "Country". We are trying to create some SharePoint 2013 Apps (for running under Office 365) which use a list to store information.
For example we want to have a News app which has a NewsContentType and a list under the app web. The NewsContentType must have a field called "Business Unit" which is bound to the taxonomy term.
What are the possibilities to implement this? At this moment I use the Content Type Hub to publish a ContentType with all Site Columns we use to all site collections. We have done this to have the site columns available in all site collections. So in my app I can create a ContentType that has the Business Unit site column. The only problem is that Guid's are used in the Content Type to refer the Site Columns. So on a differente Office 365 environment it is not working.
Are there any other solutions or ideas?
Thanks in advance,
Evert
