We are interested in providing a project published in SharePoint to a client, so they can then edit the files and TOC of the project. How much of this is possible?
Are there any recorded webinars on the subject?
You can publish to Sharepoint provided you are using a recent version of RoboHelp. See the RoboHelp Tour on my site. That does not enable your client to edit the files though.
When you generate from the topics, RoboHelp changes the topics to work with a browser and creates the output files that support the search and so on.
Clients customising help is something I have come across several times but when they realise it has to be done in RoboHelp, the enthusiasm tends to wane, rapidly. Why pay for a RoboHelp licence and learn how to use it as opposed to paying you seems to be the conclusion with that route.
Whilst they might be able to edit a topic to a limited extent, that would not extend to the TOC and the search would be for the output as delivered.
There's an old article about customising help on my site that will give you some more background.
Co-authoring is a source file feature.
