Web E-speak: facilitating Web-based e-services

E-Speak, Hewlett-Packards e-services initiative, is an open, distributed platform that lets e-services dynamically and securely advertise, discover, and interoperate with each other. Web E-Speak, the gateway to E-Speak on the Web, facilitates engineering Web-based e-services by taking into account their requirements for dynamic ad-hoc discovery, secure interaction, and global accessibility.

E-Speak - An XML Document Interchange Engine

E-Speak is Hewlett-Packards open source infrastructure for web-based e-services that allows e-services to advertise, discover, and interoperate with each other dynamically and securely (www.e-speak.net). It provides XML interfaces for creating, mediating, and accessing e-services in combination with concepts of vocabularies, name virtualization, dynamic discovery, and visibility control. The paper overviews the E-Speak architecture and its abstractions. Then we describe Web E-Speak, E-Speaks gateway to the Web, and show by examples how Web E-Speak supports the creation, deployment, and discovery of web-based e-services and their interaction.

Status of object-oriented COBOL (panel)

This panel will provide information on the current status of the emerging object-oriented features to COBOL to be formalized in what is anticipated to be the 1997 version of the ISOjANSI COBOL Standard. l’hc intent of the X3-authorized task group, X3J4.1, is not to add a few object-oriented extensions to COBOL, but rather to make COBOL, an object-oriented language. The committee’s goal is to have Object-Oriented COBOL be the language of choice for programming organizations moving to the object-oriented paradigm. The committee’s design fosters the co-existence and interaction of both legacy and object-oriented COBOL programs. Legacy programs will be able to be altered to invoke methods; methods will be able to call legacy programs. The panelists are each X3J4.1 participants, some from the committee’s inception.
