Hello Brian, Thank you for your clarifications. I guess while I used the term "standardization", I actually meant it rather informally, something like "openly accessible", "well defined", and perhaps also "promoted by a community", rather than the formal meaning of the term -- going through a formal standardization process. The insight I thought I had was that the WSDL interfaces scheme and predetermined vocabularies, developed by ALF, to support interoperability, is a key design outcome, while the working exemplar is a sample implementation of those interfaces. Daniel Brian Carroll wrote: Hi Daniel, It is important to remember that Eclipse is not a standards body. Eclipse prefers the notion of an "exemplar" - basically working code - and therefore does not set a standard but rather shows how something could be accomplished while leaving open the possibility of implementing it another way. A focus of ALF is on interoperability and that does require agreement among the communicating entities, so ALF is defining a set of exemplar vocabularies for a variety of domains involved in the application development lifecycle. Your phrase of "workable and viable interface[s]" describes it quite well, but ALF does not set standards. >From a practical perspective, we see a lot of insight and thought in the form of input from interested vendors going into the vocabularies, and if someone wanted to take the ALF vocabulary and ALF component interfaces through a standards process such as OASIS or the OMG (Eclipse IP rules permitting), then the contributions of the ALF would not be a bad place to start.

In this sense one prime objective of the ALF framework appears to become a ALM standard, and designing the ALF framework means coming up with workable and viable interface standards, that applications and execution engines can adhere to. Can you agree to that observation? thank you, Daniel p.s. BTW, I am still following the ALF project for my research ... just more in the background ... Tim Buss wrote: |
