OWS-6 Movies are finally available!

With the OGC TC in Boston this week, the pressure was up to make those movies available.

The first one is related to RESTFul workflows:

The second one provides more information on the underlying security archtecture:

Security Requirements for RESTful Web Services

Posted by Patrice Cappelaere Fri, 22 May 2009 02:11:00 GMT

A RESTful web service approach is great but it needs to be somewhat secure to survive in the wild Internet.

Here are some of our requirements that we tried to address with our OGC OWS-6 demonstration.  I will try to upload the videos to YouTube next week.

Here is another presentation given at the 2009 International Symposium on Collaborative Technologies and Systems (CTS 2009) in Baltimore this week.  More later…

Two Degrees to SensorWeb 2

Posted by Patrice Cappelaere Thu, 08 Jan 2009 02:55:00 GMT

For SensorWeb to be relevant, we believe that any of its data and assets can be no further away than two degress of separation from anyone in the world. This does assume that those users would be from trusted domains and would have been granted the proper permissions from their organizations.  We are coining this our SWE "Bacon" number or Two.  So, you are doing SWE?  What is your Bacon number?

Workflows, RESTful OGC Services and Identity 2.0

Posted by Patrice Cappelaere Sun, 25 Nov 2007 15:33:00 GMT

Generating just-in time data products for first responders require the chaining of many web services using workflows.

Our interesting challenge is multi-fold. First responders from various organizations will need access to data provided by other organizations in case of emergencies. Single sign-on is a must. Trusted relationships between organizations is critical to grant access of sensitive data or assets to remote users in a seamless manner.

Access profiles may need to be exchanged at login to determine the access rights of those incoming users.

With the OGC, we are working on RESTful APIs for SensorWeb Enabled Data Nodes. Fairly sophisticated workflows will access remote web services to task satellites, process the data and deliver custom products to the end-users. This needs to be done securely on behalf of the end-users that may grant temporary or permanent access to costly resources to those workflows.

As part of OWS-5, we will be demonstrating that capability fairly shortly. This will require the tight integration of Identity standards such as OpenID 2.0 and the emerging OAuth.

This is part of our effort to provide a simpler but secure resource oriented architecture (ROA) that will scale up to support a broader community in a federated environment.
