Go to http://www.battelle.org/arlington/cioot/cioot_main.stm for a description of the Computer Patient Records Using Object Oriented Technology (CIOOT) project. This describes the project that used CHCS wrappers we generated using the EsiBuilder tool set. It was the first project that produced the EsiBuilder tools and CHCS wrappers.
This presentation http://www.stc-online.org/cd-rom/1999/slides/BRequMng.pdf describes the Use Case approach to Requirements management. No links for the work we did for VA on GCPR which later became FHIE. This produced the CORBA ORB (EsiORB) and one of the first Clinical Observations Access Service (COAS) implementations for data extraction from VistA. This http://www.nemug.org/Apr02_A.html contains a summary of projects given at NEMUG. Articles on Easy CHCS at http://www.mmt-kmi.com/archive_article.cfm?DocID=87 and http://www.military.com/MilitaryReport/0,12914,MR_Pilot_082602,00.html. If you go to http://www.esitechnology.com, click on the Library button and click on the whitepapers or presentation links and you see a list of papers and presentations on the subject. Terry L.

Terry: Could you point to any web based source of information about this project and its details. If no such sources currently exist can you note Point-of-conatact information (including e-mail addresses and names) for those who would like to followup. I am sure that others also would find such information valuable.
