Minutes and schedule for next couple of weeks (incl. parameter sweep)
by Andreas Savva 25 Aug '08

25 Aug '08

The chairs are away this week and most of next week so the next call is scheduled for September 10th. Sep. 10 will be on OGF24 preparation and Activity schema. As discussed on Aug.20 call, the parameter sweep issues seem to have been dealt with and there is no plan for a further call for parameter sweep. If the remaining issues that have been "resolved"/"fixed" can be independently reviewed and "closed" before Steve or I return then (Michel) please go ahead and issue a final call on the list. Please allow a bit more time for this document's final call. Sep. 10 is probably a good date to set as a target day to finish the final call given we will also have a call on that day. Minutes of Aug.20 call: https://forge.gridforum.org/sf/go/doc15319?nav=1 -- Andreas Savva Fujitsu Laboratories Ltd

Parameter Sweep new artefact
by Michel Drescher 21 Aug '08

21 Aug '08

Folks, while reading the ParameterSweep spec draft 13, I came again to the definition of the sweep:DocumentNode definition. The DocumentNode is defined as of type xs:string containing a XPath 2.0 expression. This is the issue that I had numerous discussions with various people about. Despite having different reasons for why changing this, I agree with all of those people that it would be not wise to leave the definition of DocumentNode as it is without amending it. In short, XML tooling does not universally provide namespace bindings declared in the containing XML document ([XML Namespace] spec is in complete silence whether namespace bindings are in scope for XML *content*), or do not guarantee that namespace bindings are up to date to match the prefixes used in the XPath expression. That means that the XPath processor has no guarantee that it can resolve all prefixes used in the XPath expression can be resolved to the correct namespaces, or even to any namespace at all. The solution is to make the namespace bindings explicit that have been used to construct the XPath expression. That way, the ParameterSweep specification is independent of the tooling used by any implementer (which is a good thing :-). I therefore propose to amend the DocumentNode element with an attribute that makes the bindings explicit as follows: The attribute shall be named "mapping", and shall be defined as a mandatory anonymous XML attribute on the DocumentNode element. The attribute shall be of type "list of Strings" further constrained as follows: - It MUST have an even number of string parts. - The list MUST be formed as follows: Part 0: Namespace URI Part 1: Prefix for part 0 Part n+2: Namespace URI Part n+3: Prefix for Part n+2 The following is a brief example how the DocumentNode element would be used in a Sweep: <sweep:DocumentNode mapping="http://schemas.ggf.org/jsdl/2005/11/jsdl-posix foo http://schemas.ggf.org/jsdl/2005/11/jsdl-posix bar"> //foo:POSIXApplication/bar:Argument[4] <sweep:DocumentNode> Note that the example is quite artificial as it binds the same namespace to two different prefixes. Nonetheless, it is a valid example. I will also add a tracker issue for this. Comments please? Cheers, Michel -- Michel Drescher Fujitsu Laboratories of Europe, Ltd.

ParameterSweep draft 13
by Michel Drescher 20 Aug '08

20 Aug '08

Folks, thanks to Dave who pointed out some artefacts I didn't update when integrating the "File Sweep" proposal I created a new version of the Parameter Sweep specification. The changes are of purely editorial nature and do not change the contents at all. Please find draft 13 attached and published on Gridforge in the usual place.

Parameter Sweep specification, draft 12
by Michel Drescher 15 Aug '08

15 Aug '08

Folks, please find attached, and published on Grodforge () draft 12 of the Parameter Sweep specification. The main change is including Davids text for the file sweep substitutes including a host of illustrating examples. I have *not* changed schemas for possible extensions; several attempts to accommodate the current constraints requirements I failed to come up with a solution I would deem acceptable to all sides.
