[Css-csts] Substitute word for "live" data?

[Anthony Crowson]

Hello John,

Here are are couple of slightly shorter suggestions (bear in mind the effect of "contemporaneous" on UML diagrams!) - I don't think there's a huge semantic difference between the three. My vote would be for the shorter, "concurrent", unless it's ruled out by some pre-existing association for someone. 

- Concurrent - "occurring or existing simultaneously or side by side"

- Simultaneous - "existing, occurring, or operating at the same time; concurrent"

The winner for shortness might be coeval, "Originating or existing during the same period; lasting through the same era", but I don't think it's really quite right: it fits longer timespans. I rejected synchronous or synchronised, because complete delivery, as opposed to timely, may well not stay synchronised (or -ized, which is another argument for avoiding that variant!)

---

If I may, I would also like to offer an alternative to "retrieval" for consideration: "recall". It's a word typically used here for the "off-line" services (which I appreciate may not be much of an argument anywhere else!) and it is marginally shorter.

---

To muddy the waters further, there are minor objections that concurrent/contemporaneous don't actually convey the distinction we're after:
- "complete" online delivery may well outlive the space link 
- but retrieval could also happen while the space link still exists

One could consider connected / disconnected as a closer distinction, but I'm not convinced it's intuitive. It fits in with the concept of disconnected networks, though. If "offline" data is still an extension of the space link, then it's a disconnected extension.


I bet you're glad I didn't say all that in the telecon!

Anthony

Subject: [Css-csts] Substitute word for "live" data?

Members of the CSTSWG --
I have come across a term that I think might be appropriate for what has
been recently called "live" (as in "live data") in the CSTS Procedures
Definition document. The word is "contemporaneous", which is defined as
"existing, occurring, or beginning at the same time or during the same
period of time as something else". It is a rather long word, but I think
that it is a proper word for what we are trying to express.
Specifically, "contemporaneous data" could be defined for CSTS purposes
as "data that exists or occurs at the same time as it is generated by
its source." 

Given that there has been some uneasiness with the term "live", we might
want to consider this as an alternative.

Best regards,
John
