Vapour is a validation service to check whether semantic web data is correctly published according to the current best practices, as defined by the Linked Data principles, the Best Practice Recipes and the Cool URIs.
Although the main way to use Vapour is throught the public web service, the source code is avaible as open source software under the terms of the W3C License, so you can set up your own service or modify the source code in Python, if needed. Some more details are available at ohloh.

High-level architecture
Vapour has the following high level architecture:
Vapour contains three modules:
- cup
- provides the web interface of the application
- teapot
- is the core of the application that launches HTTP dialogs, evaluates the responses and stores the results into the (in-memory) RDF store
- strainer
- generates the reports, both in XHTML and RDF/XML
History
Vapour was originally created to check the compliance of a web site against the recipes described in the Best Practices Recipes for Publishing RDF Vocabularies (W3C Working Draft), but later it was extended to be more generic to any kind of resources. This work is not endorsed by W3C.
