One of the features available in SharePoint Data Doc is the ability to use a shared copy of the XML file, which can be stored in a document library on one of your SharePoint sites,
Accessing a central XML store enables you to instantly roll out new Queries, Tables and other SPDD objects. This means that an administrator can centrally manage the document templates available, while users need only select and run from those made available. Any changes made by the administrator are instantly rolled out to any other users pointed to the Central XML location.
The first thing to understand when accessing a central XML store, is that you still need to have a local version of the file on each clients machine. The primary reason for this is to allow connection to your SharePoint Site in the first instance, i.e. in order to access the XML file stored in your SharePoint document library.
In order to setup access to the shared XML file, first click the Default Options button in the Settings section of the Excalibur ribbon.
Next, navigate to the XML Options Tab to see the available options.
If you wish to use an XML File from a central location, choose the Use Document Library XML File option.
Next, select the correct Site for your host Document Library location. Note: you need to have previously added this Site in the Connecting to SharePoint section.
Next, Select the Document Library from those available on the selected Site. Ensure that you have a copy of the XML file uploaded into the relevant Document Library.
Then Save your changes.
Once saved the application will then get it's mapping details from the XML file located within the Document Library.
Note: A simple way to implement this for a large number of users is to set these options up in the Admin version of the XML file, then when installing, copy the admin XML to each local machine. That way everyone will be already set up to look at the correct location for the XML file for any future changes.
