Subject: Re: [sca-assembly] [ASSEMBLY-225] Concept Definition Needed for "Runtime" inAppendix B - Proposal



Eric,

Excellent thoughts, Eric.

So let me recast the whole proposal:

B.12 SCA Runtime

An SCA Runtime is a set of one or more software programs which, when executed, can accept and run SCA artifacts as defined in the SCA specifications.
An SCA runtime provides an implementation of the SCA Domain and an implementation of capabilities for populating
the domain with artifacts and with capabilities for running specific artifacts.  An SCA Runtime can vary in size and organization and can involve a
single process running on a single machine, multiple processes running on a single machine or multiple processes running across multiple machines
that are linked by network communications.

An SCA runtime supports at least one SCA implementation type and also supports at least one binding type.

SCA Runtimes include:
o development runtimes, which are tools provided to assist developers in the creation, test and debugging of SCA applications
o production runtimes, which are used to host and run SCA applications for the provision of business capabilities

An SCA runtime can be implemented using any technologies (i.e. it is not restricted to be implemented using any particular technologies)
and it can be hosted on any operating system platform.

Hi Mike,

Thanks for taking a run at this one.

In one regard, I think your proposed text still leaves a large question - is an SCA Runtime a single process, multiple processes on one machine, or multiple processes running across multiple machines, connected by network communications?

Unless I've completely missed the boat, the answer is "all of the above" - which is enormously useful to clarify, and we should squeeze that in somewhere.

Also, "an SCA Runtime is a software program which can accept and run...".  I have two problems with this:
So I'd restate the first paragraph as:
"An SCA Runtime results from the execution of a software program, or set of software programs which can accept and run SCA artifacts as defined in the SCA specifications.  This program, or set of programs might create an SCA Runtime within the scope of a single computing process, across multiple processes, and even across multiple machines.  An SCA Runtime provides an implementation of the SCA Domain and an implementation of capabilities for populating the domain with artifacts and with capabilities for running specific artifacts. "

Just a thought.

-Eric.

P.S. "SCA Runtime" vs. "SCA runtime" - shouldn't this just be the first form throughout the definition?

Folks,


Here is a proposal to resolve Issue 225.


Add a new section to Appendix B (SCA Concepts), as follows:



B.12 SCA Runtime


An SCA Runtime is a software program which can accept and run SCA artifacts as defined in the SCA specifications.

An SCA runtime provides an implementation of the SCA Domain and an implementation of capabilities for populating

the domain with artifacts and with capabilities for running specific artifacts.


An SCA runtime supports at least one SCA implementation type and also supports at least one binding type.


SCA Runtimes include:

o development runtimes, which are tools provided to assist developers in the creation, test and debugging of SCA applications

o production runtimes, which are used to host and run SCA applications for the provision of business capabilities


An SCA runtime can be implemented using any technology (ie it is not restricted to be implemented using any particular technologies)

and it can be hosted on any operating system platform.
