Special Applications and Services Meeting Announcement John Klensin APP Joyce Reynolds USV Erik Huizer APP This is to announce a combined Application Area and User Services Area session at the upcoming IETF. The session is meant to coordinate efforts in Application related groups in these two Areas of the IETF. The session takes place on Thursday 0930-1200. The session is split into two parts: Applications Area Directorate Open Meeting (apples) (0930-1045) Integrated Information Architecture (iia) (1045-1200) First part of the session: ========================== Open Applications Area Directorate meeting (apples) --------------------------------------------------- Within the IETF there are currently a lot of application related efforts going on. In the past year there has been some reshuffling of Applications related IETF activities: - Integration of OSI related work in Applications Area - Creation of WGs that are chartered in both the User Services AND the Applications Area. - Creation of the Service Applications Area The Applications Area Directorate and the IESG are trying to keep these in line and coordinated. However, it has been our experience that often enough participants in Application related WGs are not aware of similar or related work in other IETF WGs. As a result of this it happens sometimes that valuable input from one part of the IETF community to a certain spec, is only given at a very late stage, which is of course not beneficial to the result. To make people aware of what is going on in the IETF with regard to applications, this meeting intents to give an overview of ongoing work, and issues under discussion in the various WGs. The goal of this meeting is to assure the right level of expertise in each WG to cover all aspects of the work within that WG. We strongly encourage all people who participate in any Applications related WG, to attend this session. Second part of the session: =========================== Integrated Information Architecture (IIA) meeting in Houston When IESG created the IAFA, IIIR, NIR, URI, and WNILS working groups, it did so as components of an overall effort to develop a single coordinated Internet architectures for information naming, discovery, and retrieval system. The working groups involved have made rapid progress, but occasionally at the expense of coordination with each other, with other IETF WGs, and with existing practice outside IETF. It has seemed to the responsible area directors that coordinated efforts are even more important today as these efforts overlap and intertwine. This session is an open discussion of IIA issues with the chairs of the five WGs and the three area directors to determine what level of coordination of overlapping facilities is still appropriate and how to accomplish it. The results will include a progress report to IETF on the development of the integrated information service, as required by the charter statement. A copy of the original charter and IESG position statement follows for reference. --------------------- Integrated Information Architecture Many new networked services to identify, access, and retrieve information resources have sprung up in the last several years -- archie, WAIS, and Netfind, to name only three. Now, much as the Internet has tied many disparate networks together into an integrated system, the pressing problem is how to integrate these many new services into a single coordinated Internet information naming, discovery, and retrieval system. There are three vital areas of this integration effort that the IESG is interested in pursuing: 1) The identification, cataloging, and documentation of networked information services, new and old. 2) The standardization of descriptions and identification schemes for networked resources, and the distribution and implementation of these identifiers. 3) The integration and interoperability of the various new information services. To this end, the IESG is creating three new working groups: 1) Networked Information Retrieval (NIR) -- NIR will work on the first issue above by identifying, cataloging, and documenting networked information services. The result will be a published catalog of network information retrieval services. In addition, NIR will liase with other organizations working on this goal, such as RARE ISUS and CNI. 2) Uniform Resource Identifiers (URI) -- URI will concentrate on the second issue above, particularly on the standardization and implementation of identification schemes for networked resources. There will be two primary components in this effort: a Uniform Resource Locator (URL) which is a string which tells how to locate a document. The second part is a Universal Resource Serial Number, which is used to uniquely identify a resource, so that one can, for example tell if two documents with different file names are, in fact, the same. The standard identification scheme developed by URI will be used by NIR to define the standard resource formats. 3) Integration of Internet Information Resources (IIIR) -- IIIR will work on the third issue by developing technical specifications and documentation for a) interoperation between the various information services and b) the integration of new information services into the existing CIM (combined information mesh). After the specifications for interoperation have been completed, IIIR will examine the need for additional protocols necessary to further integrate the CIM, including gateway protocols, query routing protocols, and other mechanisms. In addition to the above named groups, the IETF wishes to facilitate the standardization of descriptions and data formats for various specific information services by chartering single-protocol working groups which will work on this standardization. Examples of such groups are the Internet Anonymous FTP Archive group (IAFA), which is working on standardization of anonymous FTP archives, and the new Whois Network Information Lookup Service (WNILS), which is working on standardization of services using the WHOIS protocol. The IESG considers these WGs to be components of a single coordinated IETF effort to create an integrated Internet information architecture. Therefore, the chairs and membership of each group will be active participants in the other groups. The overall coordination of this effort will be under the joint management of the Applications and User Services Area. Due to the importance of an Integrated Internet Information Service Architecture, the IESG requests the working group chairs and the Applications and User Services area directors to jointly expand this brief overview into a more fully fleshed out architectural statement, and to issue periodic progress reports describing how the integrated information service is developing. -----------
