I have been creating dummy content for one of our publications. The
document files under content/authoring all have the long uuid hash as
folder name (e.g. 39218710-3e61-11db-9355-d674a0018e0e/).
For convenience, I usually change the first letters of the uuid and give
it a more meaningful name (e.g. news-710-3e61-11db-9355-d674a0018e0e).
For this, I update the folder name and the uuid in sitetree.xml.
Any risk that I might run into trouble for doing this?
You don't have UUIDs anymore. For instance, if only the first number
of two UUIDs is different, and you rename both to news-[...], you
get a clash. I would strongly discourage changing UUIDs.
Another question: is the generated uuid a random hash, or is there any
semantics in it?
There are different semantics:
1. Time-based with unique or random host identifier
2. DCE Security version (with POSIX UIDs)
3. Name-based (MD5 hash)
4. Random
5. Name-based (SHA-1 hash)

Lenya's default UUID generator uses the Axis UUIDGenFactory:
