OMG Internet PSIG
Minutes of Meeting #30
December 11, 2000
Chairs: Shel Sutton, Craig Thompson, Harri Kreus (newly elected)
OMG document: internet/00-12-01
We elected Harri Kreus as co-chair (Thompson made the motion, Garber seconded,
white ballot). Harri brings a vision that mobile computing will pervasively
combine with the Internet Web and middleware infrastructure will be needed
to make this happen.
Mobility and B2B Portals, Harri Kreus, HM&V Research, Finland - see
Question: How do we join corporate infrastructure to mobile access?
Answer: via enabling intermediary infrastructures. Talked about emerging
standards in the European Community: WAP, WWTLS for security, WML, VoiceXML,
UP.Browser, .... Not yet is there a global or interoperable mobile
communication layer. UGSM is a candidate. OMG has a potential
broad role to play here.
Coalition Security Policy Language, Shel Sutton, MITRE - see internet/00-12-03
What is a policy? a rule that manages or modifies behavior.
The language for rules is intended to be independent of implementation.
Talked about identification, authorization, obligation, restraints, delegations,
constraints. Current security technology is role based. Reviewed
several security policy languages - SPL, TPL, PLAS, PDL, Ponder, s2ml.org.
The Coalition problem is that security policies are different, country
to country so a puzzle is interoperability. What happens when there
are multiple policies for an entity, policy precedence, semantic conflicts.
Do domains have to have prior knowledge of each other. Mobile devices
discover and know about each other. Do I know you - do know about
you - introductions and negotiations. Shel has a 2 year project and
is trying to involve 30+ others.
Q: how does this fit w what Harri talked about? Shel:
Comment by Craig: policy management is much more general than
security - other ilities and QoS need management or administrative interfaces.
Shel agrees. Craig also mentioned the general work in agents on agent
communication languages and ontologies and the specific work by Bradshaw
on domains and coalitions and a side meeting with FIPA will happen Wednesday.
Comment by Roger: there is a B2B body of work too.
Shel mentioned the recent history of the Internet SIG (in the last two
years or so) where we focused our work into working groups - agents wg
became Agent SIG; Compositional Semantics resulted in a paper Next Generation
Object Management Architecture that affected subsequent OMA revisions;
CSCW, OTAM, and WOIA all made some progress and then lost their chairs.
He discussed roles of ISIG - presentations and new ideas as well as producing
green papers, FRIs, RFPs, and other results. So what should ISIG
do next? What topics are people interested in?
mobile wireless - Harri is interested in mobility services. Also
see related interest in Agent SIG (where mobility is not just focused on
agents but also objects)
policy management - Shel is potentially interested in championing policy
management. Again, there is related interested in various places
in OMG - see security and event domains as well as Agent SIG/FIPA work
on domains and policy management.
ubiquitous - Bob Marcus is interested in organizing a workshop on Middleware
Infrastructure to support Ubiquitous Computing or possibly a WG.
Organization meeting next time, then Paris as venue for the workshop.
Next Meeting Agenda
Get agenda items from Harri, Shel, and Bob to expand these three topics.
