Flag CreativeWork version with `isLatest`

I've been wondering if there is a good way to flag a specific version of a creative work with "isLatest": true

I would turn the question around: if you implemented a crawling system, would you believe a page that has annotation that
isLatest: True ? I would not.

A recent [dateModified](https://schema.org/dateModified) field would be a much stronger signal, along with a annotations that make the current markup the authoritative one.

Would you ever state "isLatest": false on your current content?

The only example I can think of is if you are listing historical versions of content. And that does not seem to be the best way to indicate the order they come in.

You can use the version field to indicate that, as well as the dateModified fields.

hm, it is common practice to have some sort of https://example.com/my/dataset/latest that symlinks to https://example.com/my/dataset/2.0.3 - everyone can sort by date or semantic version but it is this type of "provide some convenience method for my customers (that is not necessarily a symlink and more declarative)" that I'm looking for.

okay, I figure between

PREFIX xsd: <http://www.w3.org/2001/XMLSchema#> 
SELECT (strbefore(str(max(xsd:dateTime(CONCAT(?mod, "T00:00:00Z")))), "T") as ?latest)
WHERE {
    ?x <http://schema.org/dateModified> ?mod.

and

SELECT ?latest
WHERE {
    ?latest <http://schema.org/isLatest> true.

there is not that much difference.
