Nationwide telecare for diabetics: a pilot implementation of the HOLON architecture.

This paper presents results from a demonstration project of nationwide exchange of health data for the home care of diabetic patients. A consortium of industry, academic, and health care partners has developed reusable middleware components integrated using the HOLON architecture. Engineering approaches for multi-organization systems development, lessons learned in developing layered object-oriented systems, security and confidentiality considerations, and functionality for nationwide telemedicine applications are discussed.

HOLON: extending Web document libraries via objects in order to support the health information infrastructure. Health Object Library Online.

In HOLON, user clients, applications, data servers, and fine-grained elements are all objects in a document library. To that end, this paper reviews the past year of progress and lessons learned in HOLON for integrating the Web, HL7, CORBA, Arden, KQML, UMLS Thesaurus, and other standards to determine if object technology reduces common problems in document-centric libraries such as indexing, searching/retrieving, complex data type management, and maintenance, among others.

HOLON: a Web-based framework for fostering guideline applications.

HOLON is a research and development effort in extending middleware in the healthcare field to support application development, in general, and guideline applications, in particular. This framework makes use of open standards for architecture, software, guideline KBs, clinical repository models, information encodings, and intelligent system modules and agents. By pursuing the use of such standards in our middleware components, we hope eventually to maximize reusability of the HOLON framework by others who also adhere to these open standards. This research reflects lessons learned about the extensions needed in these standards if healthcare middleware frameworks are to transparently support application developers and their users over the web.
