OGF IPR Policies Apply
• “I acknowledge that participation in this meeting is subject to the OGF Intellectual Property Policy.”• Intellectual Property Notices Note Well: All statements related to the activities of the OGF and addressed
to the OGF are subject to all provisions of Appendix B of GFD-C.1, which grants to the OGF and its participants certain licenses and rights in such statements. Such statements include verbal statements in OGF meetings, as well as written and electronic communications made at any time or place, which are addressed to:
• the OGF plenary session, • any OGF working group or portion thereof, • the OGF Board of Directors, the GFSG, or any member thereof on behalf of the OGF, • the ADCOM, or any member thereof on behalf of the ADCOM, • any OGF mailing list, including any group list, or any other list functioning under OGF auspices, • the OGF Editor or the document authoring and review process
• Statements made outside of a OGF meeting, mailing list or other function, that are clearly not intended to be input to an OGF activity, group or function, are not subject to these provisions.
• Excerpt from Appendix B of GFD-C.1: ”Where the OGF knows of rights, or claimed rights, the OGF secretariat shall attempt to obtain from the claimant of such rights, a written assurance that upon approval by the GFSG of the relevant OGF document(s), any party will be able to obtain the right to implement, use and distribute the technology or works when implementing, using or distributing technology based upon the specific specification(s) under openly specified, reasonable, non-discriminatory terms. The working group or research group proposing the use of the technology with respect to which the proprietary rights are claimed may assist the OGF secretariat in this effort. The results of this procedure shall not affect advancement of document, except that the GFSG may defer approval where a delay may facilitate the obtaining of such assurances. The results will, however, be recorded by the OGF Secretariat, and made available. The GFSG may also direct that a summary of the results be included in any GFD published containing the specification.”
• OGF Intellectual Property Policies are adapted from the IETF Intellectual Property Policies that support the Internet Standards Process.

Recap of inputs
• EPRs of activities in factory attributes is awkward at best, bad idea in general
• Activity endpoint• Pending, and other possible states• State transitioning mechanism (how is up to debate)• Interface for acquiring error information• Specifications and renderings, e.g., OSGSA-WSRF-BP rendering• Meta data schema and how you get to it
• This is a rich topic, JSDL extensions supported, applications installed, …. And so on (usw).
• Need to access session directory (out of scope for BES per se)• Vector operations• Parameter sweeps (JSDL scope)• Other way to list activities – maybe move out of spec and profile, e.g.,
no way in C to list the pointers you’ve allocated

BES 1.1
• Current porttypes• Factory
• Create, terminate, getactivitystatus, getactivitydocuments, getfactoryattributesdocument
• Management• Activity – currently undefined
• Suggested changes• Separate specification and rendering?• State model – we can accomplish requirements with existing state
model and profiling• Activity endpoint porttype specification
• Separate spec, BES should advertise which kinds of activities it can create, with potentially different activity porttypes, e.g., PGI compliant activity endpoint
• Metadata/properties model and rendering• Vector ops

Meta data model
• Concerns over size due to numbers of items and complexity for BESs that abstract many resources
• One thought, go to WSRF RP• Does not change potentially large documents• But does allow asking for subsets of information
• Streamable byteio that when read spits out document of what ever form, profile XML?
• List of required properties is … i.e. profile what glue 2 is desired

Vector ops
• Do we really need this given JSDL parameter sweep
• If not, and everyone really wants it, we can vectorize

Counter suggestion
• Don’t change it – there are lots of implementations and other profiles based upon it .. Those will all be disrupted.

Activity Endpoints
• Get_status• Terminate• Add porttypes for different types
activites, e.g.,• Change_state• Suspend• Session directories• Proceed-from-held• etc

Suggested profiling for PGI
• Rather than one uber interface lets compose a set of capabilities via interfaces
