Re: End Of Life Tag in spdx #spdx

Armijn raises a valid concern. We’ve avoided dynamic information in the past, but even with version 1.0 you could argue the “Concluded License” could change over time if new information is available after publication of the SPDX document. We’ve certainly seen project home page links change over time as well.
Since having the end of life information available is useful for a few use cases and the frequency of change should be relatively low, I’m of the opinion we could include this as an optional field.
One suggestion is to define the field as the valid information at the time the SPDX document is created. That way, even if one of these fields changes later, the SPDX document still records valid facts.

Sort of. Security information is even more likely to change after release, EOL for open source components supported by the community may, but much less frequently.
Thinking so far, is that this would start out as an optional field, so that those who do know the information
when assembling an SBOM can include it.
Example: you are using a product that contains the linux 4.9 kernel. You know from the community (https://kernel.org/category/releases.html) that it will go out of support Jan 2023 (as of today, but this may evolve),
so including this information, which could then be queried by a script around then, and then determine next steps,
is going to be much more efficient then expecting all consumers of your product to add it manually. Similarly
certain distros have expectations of EOL for support from the community (https://wiki.debian.org/LTS).
To your point, there may well be a contract with a supplier, with a date that extends this, and in that case there
are likely processes already in place to track/monitor/etc. in an organization. However those consuming open
source based products are not necessarily tracking the upstream components EOL, and probably should be.
Adding this field, as optional, enables more efficiency.
