Microsoft “The Office 365 APIs follow REST and OData 4.0 standards for data Office 365 transport, and use the OAuth 2.0 API standard for authentications and authorization.” “Microsoft Power Query for Excel’s OData V4 support leverages the built-in functionality of the OData service to bring only the relevant Microsoft data back into Excel. ” “Azure Search service API uses Excel and Open Data Protocol (OData) Azure APIs PowerQuery for index queries. Azure Search supports OData More … version 4.” SAP SAP NetWeaver Gateway SAP OpenUI5 “It eases your development with a client-side HTML5 “SAP NetWeaver Gateway provides an API that is rendering library including a rich set of controls and designed to function in just such a manner; and it does supports data binding to different models (JSON, so using the OData protocol.” XML and OData).” Salesforce’s OData product: Lightning Connect & DataDirect Cloud “With external objects you can connect to an external data source like SAP or any other database that uses OData protocol or a simple URL.” Who provides OData?

    Pyslet Documentation Release 0.6.20160201 Steve Lay February 02, 2016 Contents 1 What’s New? 1 2 Compatibility 7 3 IMS Global Learning Consortium Specifications 13 4 The Open Data Protocol (OData) 101 5 Hypertext Transfer Protocol (RFC2616) 207 6 Other Supporting Standards 247 7 Welcome to Pyslet 357 Python Module Index 359 i ii CHAPTER 1 What’s New? As part of moving towards PEP-8 compliance a number of name changes are being made to methods and class at- tributes with each release. There is a module, pyslet.pep8, which contains a compatibility class for remapping missing class attribute names to their new forms and generating deprecation warnings, run your code with “python -Wd” to force these warnings to appear. As Pyslet makes the transition to Python 3 some of the old names will go away completely. It is still possible that some previously documented names could now fail (module level functions, function arguments, etc.) but I’ve tried to include wrappers or aliases so please raise an issue on Github if you discover a bug caused by the renaming. I’ll restore any missing old-style names to improve backwards compatibility on request. Finally, in some cases you are encouraged to derive classes from those defined by Pyslet and to override default method implementations. If you have done this using old-style names you will have to update your method names to prevent ambiguity. I have added code to automatically detect most problems and force fatal errors at runtime on construction, the error messages should explain which methods need to be renamed.
