Release cycle of the specs

[roll]

The specs is the cornerstone for all the FD related software/data project. I think it's very important for any standard to define and publish as many governance details as possible. Probably the versioning is the most important at the current stage.

In my opinion, the versions of the specs should be very discrete (for example no v1.4.3) and well-emphasized in the docs. For example:

• only v1 / v2 as in jsonschema - one release per a few years
• something like ecmascript v2019 / v2020 - one release per year

I think it will not be possible to build a stable software eco-system on top of the specs if it changes too often.

We're generally keeping the specs pretty stable so more like json schema approach. More details can be covered in frictionlessdata/frictionlessdata.io#524
