Using SharePoint 2010's REST API

Get 100 items after the first 100 items from the items of this year and month:

http://site.company.tld/_vti_bin/ListData.svc/YourList?$skip=100&$top=100&$select=Year,Month,ID&$filter=Year%20eq%20%272014%27%20and%20Month%20eq%20%27Mar%27


Here's a complete example in Python, TestSharePoint2010REST.py:
