An important aspect of having it in the IG charter is to link the PlugFest, and hence implementation work and testing to the OpenDay. Otherwise, non-members, that is, numerous open source developers are looked out of this activity.

PlugFest and fostering open source implementations should thus be part of the IG charter. Yet there is also a formal aspect for the WoT WG CR process. This relation should be clarified.

Hi Dave,

I’d like ask a question to clarify the scope of test activity.

Regarding on IG’s draft charter, there was defined "one of important activity is the operation of Plugfests to test interoperability”.
And also WG side, in the figure, there was defined that WoT WG’s activity is “write specs & write test suites”.

Why it separated into WG’s Test suites and IG’s PlugFest activity ?

The W3C Process requires WGs to provide normative test suites as a basis for implementation reports for the transition from Candidate to Proposed Recommendation.  The IG’s PlugFests are intended to enable exploration of experimental work, but also to assist with preparing implementation reports for WoT WG Candidate Recommendations. I have updated the wording accordingly.

An important activity is the operation of PlugFests to test interoperability and to validate the current working assumptions of the technology building blocks discussed in the Web of Things Interest Group. These events enable developers to get together to test their implementations and facilitates networking between partners and experts. The Interest Group will seek to encourage work on open source projects and community evaluation of the Web of Things. In more detail, PlugFests enable:
• assist with preparing implementation reports for WoT WG Candidate Recommendations
• test-drive upcoming or proposed technologies for the W3C Recommendation Track
• interoperability testing across implementations for ideas at different levels of maturity
• outreach to other communities and new members (open day, demo track)

I think that PlugFest’s main role looks like “assist the implementation reports for WoT WG CR process”, according to your wording.
I can’t understand why we have to include this kind of CR assist work on the IG’s charter formally ?

It is part of the IG charter because some IG members requested that the IG charter clearly sets out the relationship between the IG and the WG to avoid any potential confusion.  The details have been subject to discussion, and I have tried to update the wording accordingly.

Is there any similar case on W3C’s other IG charters ?

The best I can think of are the Web Payments IG and WG.  Their charters can be found at:



The Web Payments WG charter states:

For more information about Web Payments activities beyond the scope of this charter, see the Web Payments Interest Group<http://www.w3.org/Payments/WG/charter-201510.html#wpig> description below.

Web Payments Interest Group
The Web Payments Interest Group<http://www.w3.org/Payments/IG/> acts as the overall coordinator at W3C of a vision for Web Payments, by gathering Web Payments Use Cases<http://www.w3.org/TR/web-payments-use-cases/>, engaging in liaisons with other payments standards bodies, and developing a high-level architecture. From time to time, the Interest Group will seek feedback from the Working Group on its evolving vision, and share information about the evolution of the Web payments technology landscape. The Web Payments Interest Group also expects to provide technical input to this and other relevant W3C Working Groups, based on a detailed analysis of the relevant Web Payments Use Cases.
The Web Payments IG charter predates the Web Payments WG charter by some time, and therefore doesn’t mention the WG at all.
