Enterprise Ontology: Theory and Methodology

If one thing catches the eye in almost all literature about (re)designing or (re)engineering of enterprises, it is the lack of a well-founded theory about their construction and operation. Often even the most basic notions like action or process are not precisely defined. Next, in order to master the diversity and the complexity of contemporary enterprises, theories are needed that separate the stable essence of an enterprise from the variable way in which it is realized and implemented. Such a theory and a matching methodology, which has passed the test of practical experience, constitute the contents of this book. The enterprise ontology, as developed by Dietz, is the starting point for profoundly understanding the organization of an enterprise and subsequently for analyzing, (re)designing, and (re)engineering it. The approach covers numerous issues in an integrated way: business processes, in- and outsourcing, information systems, management control, staffing etc. Researchers and students in enterprise engineering or related fields will discover in this book a revolutionary new way of thinking about business and organization. In addition, it provides managers, business analysts, and enterprise information system designers for the first time with a solid and integrated insight into their daily work.

This site is dedicated to the emerging subject of enterprise IT automation, otherwise called Enterprise Resource Planning for IT. This is not the automation of business process by IT; rather it is IT automating itself.



The MetaMap takes the form of a subway map, using the metaphor of helping users navigate in "metaspace", the environment of metadata.

Requirements for a Web Ontology Language

W3C Working Draft 08 July 2002. "An ontology defines the terms used to describe and represent an area of knowledge. Ontologies are used by people, databases, and applications that need to share domain information (a domain is just a specific subject area or area of knowledge, like medicine, tool manufacturing, real estate, automobile repair, financial management, etc.). Ontologies include computer-usable definitions of basic concepts in the domain and the relationships among them (note that here and throughout this document, definition is not used in the technical sense understood by logicians). They encode knowledge in a domain and also knowledge that spans domains. In this way, they make that knowledge reusable."


Metacrap: Putting the torch to seven straw-men of the meta-utopia

Cory Doctorow: "A world of exhaustive, reliable metadata would be a utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities." Opinionated, but well worth reading.


Ontology, Metadata, and Semiotics

The Internet is a giant semiotic system - it is a massive collection of Peirce's three kinds of signs: icons, indices, and symbols. This article addresses issues of representing logic, ontology, and metalanguage about them in various notations, including RDF and controlled natural languages.


Demystifying Metadata

What does 'metadata' mean from a content perspective? And what should a content producer or information manager be thinking about when they begin the hard work of gleaning the metadata out of their content store? Mappa Mundi's Marty Lucas explains.

UKOLN on metadata

The UK Office for Library and Information Networking has a metadata group whose focus is to review current approaches to resource description and to look at future options for metadata in the wider context of resource discovery.

W3C: Metadata and Resource Description

Metadata is machine understandable information for the web. The W3C Metadata Activity answers the combined needs of the PICS, DSig, and WebDAV efforts for a common syntax for expressing assertions about information on the web.

Persistent URL Homepage

A PURL is a Persistent Uniform Resource Locator. Functionally, a PURL is a URL. However, instead of pointing directly to the location of an Internet resource, a PURL points to an intermediate resolution service. The PURL resolution service associates the PURL with the actual URL and returns that URL to the client.
