I want to build a custom document management web application that ties in with sharepoint for the actual document versioning and storage. I’m hoping for something like a sharepoint widget that I can plug into my web application that would allow me to tie in with sharepoint and download documents, make edits to them, and upload them back to sharepoint, with sharepoint handling all of the versioning and storage.
Basically I’m looking for a sharepoint API.
If WSS is the answer to this, are there licensing issues that I need to consider?
Thanks.
If it’s SharePoint 2007 you’re talking about, then on the server side you have the SharePoint API (Microsoft.SharePoint.dll) and on the client side, SP provides web services for manipulating lists, libraries, users and most other things you might need.
As Jeremy said, getting data to and from SharePoint through the Web Services, requires you to write CAML queries, but it’s made easier by the help of tools such as this free CamlQueryBuilder
There’s loads of documentation on both the API and the web services online.
If you’re planning on using SharePoint 2010, all this will be quite easier, as more options are available for developers, e.g. API for the client side as well as the server side. Also new in 2010 is LINQ for SharePoint, which IMO really rocks!
