I have a question.

It looks like a lot of MPEG specs are fetched automatically from the ISO site. Right?
But I wonder how should one reference a particular version of the spec. For example for ISOBMFF I see an entry like this in iso_jtc1_sc29.json file:

    "iso14496-12": {
        "href": "https://www.iso.org/standard/85596.html",
        "title": "Information technology — Coding of audio-visual objects — Part 12: ISO base media file format",
        "status": "Under development",
        "publisher": "ISO/IEC",
        "source": "https://dashifspecref.blob.core.windows.net/iso/iso_jtc1_sc29.json?st=2019-04-01T00%3A00%3A00Z&se=2039-04-01T00%3A00%3A00Z&sp=rl&sv=2018-03-28&sr=b&sig=Q1%2F6yLw90v0VCYKPhuSw89qLXS8tPZWU%2BQSvYj%2B7NmY%3D"
    },

that points to a current version that is under development (currently 8th edition). But where is the link to the 7th edition? What is the process for adding a particular version of the spec?

adding specs based on tobie#792
6c4d3e7 
This commit adds:
- SMPTE ST 170
- SMPTE ST 240
- IEC 61966-2-1
- ITU-R BT.2100

ISO/IEC 23091-2 (CICP) spec is already in iso_jtc1_sc29.json however its
not so clear to me how to reference the latest version that is not under
development. See relevant discussion in tobie#832
