HI. I'm a student from Spain. I'm making mi doctoral thesis. My topic is the use of standards for emergencies. I have found tow xml based standards. EDXL (from OASIS) and CIPI (from OGC). Apparently there is no more documentation since 2003 (about CIPI). I would like to know more about this initiative but I am not able to find more documentation.

Could somebody help my




Thank you very much. This helps me a lot. I will study all the documentation carefully.

Besides being the CTO of the OGC, I am also the official OGC representative to OASIS. I contributed to both the CAP and EDXL-DE efforts. So, I will try to answer your questions.

First, CIPI. The Critical Infrastructure Protection Initiative was an OGC Interoperability Testbed. Testbeds are rapid engineering activities in which selected OGC members work to solve a specified set of geospatial interoperability problems using existing or emerging OGC standards and then demonstrate the result of this work in a real-world based scenario. You can visit and for a little more information on the CIPI testbeds. There are also a number of OGC Discussion Papers that describe a collaborative architecture for critical infrastructure protection. The CIPI effort was completed in 2003.

Second, OASIS. Within OASIS there is an Emergency Management technical committee (EM TC). Within that committee, work has been done on CAP and EDXL. CAP is an alerting Protocol. The OGC has used CAP in two interoperability initiatives (OWS-3 and SIDP). EDXL is a distribution encoding for additional information related to an emergency event. There are many implementations of CAP and only a few implemementations of EDXL. There is now a proposal to enhance both CAP and EDXL location elements using a simple profile of GML 3.1.1. I just submitted a change request proposal to do this. The proposal has been approved by the GIS Subcommittee of the OASIS TC and will now be deliberated by the entire EM TC.

Third, comparisons of CIPI and EDXL. This would be like comparing apples and oranges (or worse). CIPI was an OGC Testbed activity focused on how best to use standards to solve interoperability issues related to emergency services. EDXL is a very new standard focused on solving a very specific communications issue related to the transmission of information about an emergency incident. I should also point out the EDXL is very, very young and has only two known commercial grade implementations.

Now, just because the OGC does not have a specific CIPI testbed activity does not mean that we have ignored emergency services and disaster management. The majority of OGC Interoperability Initiatives are based on emergency services use cases and scenarios. OWS-3, completed in October 2005, used a Wild Fire scenario for the demonstration. A video synopsis of the demonstration and the OWS-3 activity can be found at Additional information on OWS-3 can be located at

Another major initiative completed in 2004 used weather and fire events as the basis for demonstrations. This was a very large interoperability demonstration project partially funded by the Australian Government. This project was called SIDP _ Spatial Interoperability Demonstration Project. There are many documents and presentations available at .

Finally, the OGC is starting the OGC Web Services 4.0 next week. Go to for more information. There are over 20 OGC member organizations participating in this initiative. There will be a demonstration at the end of the testbed activity. The demonstration will once again be focused on emergency services, but on a very local type of an emergency - fire in a building.

I have attached a draft OGC White Paper on the benefits of using standards for emergency management.

I hope that all this information helps.
