That works for me

Thanks,

Hi,

I had an action item to re-write the note related to "domainMapping" in "multi-engine" scenarios. Here is comes ...

Cheers,
Christian
==
Although the focus of ITS 2.0, and some of the usage scenarios addressed in ITS 2.0 showcases (see http://www.w3.org/International/multilingualweb/lt/wiki/Use_cases_-_high_level_summary#ITS_2.0_Metadata:_Work-In-Context_Showcase) is on “single engine” environments, ITS 2.0 - for example in the context of the "domain" data category - can accommodate "workflow/multi engine" scenarios.

Example:

- A scenario involves Machine Translation (MT) engines A and B. The domain labels used by engine A follow the naming scheme A_123, the one for engine B follow the naming scheme B_456.
- A "domainMapping" like the following is in place: domainMapping="'sports law' Legal, 'property law' Legal"
- Engine A maps 'Legal' to A_4711, Engine B maps 'Legal' to B_42.

Thus, ITS does not encode a process or workflow (like "Use MT engine A with domain A_4711, and use MT engine B with domain A_42"). Rather, it encodes information that can be used in workflows.

Hi Felix and all,

Here is my suggestion for a note (native speakers please correct):

Bear in mind that ITS is first and foremost a powerful markup technology
to add metadata to (Web) content. In this sense, it is not a (direct)
means to support, or even drive process or workflow engines, although
some of the data categories like provenance, domain, domain mapping,
etc. may induce such a view. Since this ITS metadata enhances the
content in a structured way and in multiple forms, ITS consuming agents
can employ that data to effectively implement their usage or deployment
scenarios within single engine or single process environments as well as
within multi-engine environments such as "try MT engine A, then MT
engine B, ..." (see also ITS 2.0 showcases at
http://www.w3.org/International/multilingualweb/lt/wiki/Use_cases_-_high_level_summary#ITS_2.0_Metadata:_Work-In-Context_Showcase).
It is, however, not possible to assign, say, a specific domain mapping
incarnation to a certain (process or workflow) instance because such an
assignment concerns the process side, and this is beyond the current ITS
metadata scope.

With this, we now have apparently reached consensus on 2.a., 2.b.
(already reviewed by Christian), and 1. (shepherd's view...)

[@Yves: 1. is independent of the domain mapping specs.]

Cheers -- Jörg
