Directories provide a general mechanism for describing resources and enabling information sharing within and across organizations. Directories must resolve differing structures and vocabularies in order to communicate effectively, and interoperability of the directories is becoming increasingly important. This study proposes an approach that integrates a genetic algorithm with a neural network ...

Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress." Discussion of this document should take place on the LDAP (v3) Revison (ldapbis) Working Group mailing list . ...

Much of the data we deal with every day is organized hierarchically: file systems, library classification schemes and yellow page categories are salient examples. Business data too, benefits from a hierarchical organization, and indeed the hierarchical data model was quite prevalent thirty years ago. Due to the recently increased importance of X.500/LDAP directories, which are hierarchical, and...

Organizations associated with the use of Geographic Information Systems (GIS) have collected a large volume of spatial data. Descriptions of these data sets, called metadata, are seen as an important component to facilitate their access (Shah & Sheth, 1998). Most organizations have utilized some form of local or international metadata standard. To represent the diversity of the available metada...

Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as refer...

OpenLDAP is the premier implementation of LDAP client and server software, providing full support of LDAPv3 and most popular standard and draft (work in progress) LDAP extensions. It has evolved over the years from its origins in the University of Michigan's reference implementation of LDAPv2 as a vehicle for experimentation into a mature, commercial grade package capable of supporting the most...

With the increase in popularity of XML on the Internet, the requirements of database management systems have shifted from traditional transaction-based databases towards the kind of characteristics provided, by design, by the Lightweight Directory Access Protocol. At the same time, the design and use of a middleware to provide a common querying interface to XML-based systems has become an incre...

The need to manage large information repositories in a secure, distributed environment increases with the growth of the Internet. To address this need, a system capable of managing the contents of an LDAP directory over the Web has been designed and developed. This system allows for the directory’s data to be divided into communities and supports the delegation of administrative authority over ...

This informational memo contains a description of some measurements from early DiffServ (DS) experiments that used a preliminary version of IBM's DiffServ implementation on an IBM router over an egress T1/E1 PPP interface. The service level specification (SLS) may be configured on the router or optionally controlled by an external LDAP policy server. The measurements were intended to examine th...
