Enabling the Internet White Pages Service -- the Directory Guardian
The Internet White Pages Service (IWPS) has been slow
to materialise for many reasons. One of them is the
security concerns that organisations have, over allowing
the public to gain access to either their Intranet or their
directory database. The Directory Guardian is a firewall
application proxy for X.500 and LDAP protocols that is
designed to alleviate these fears. Sitting in the firewall
system, it filters directory protocol messages passing into
and out of the Intranet, allowing security administrators
to carefully control the amount of directory information
that is released to the outside world. This paper describes
the design of our Guardian system, and shows how
relatively easy it is to configure its filtering capabilities.
Finally the paper describes the working demonstration of
the Guardian that was built for the 1997 World
Electronic Messaging Association directory challenge.
This linked the WEMA directory to the NameFLOWParadise
Internet directory, and demonstrated some of
the powerful filtering capabilities of the Guardian
Secure Directories
This paper describes the mechanisms that are needed in order to provide a secure directory service based on the X.500 data model. A brief introduction to the X.500 data model is given followed by an overview of the Lightweight Directory Access Protocol. Security can be provided by three functions: an application level firewall, an authentication mechanism, and an access control scheme. A description of the X.500 and LDAP access control models is presented followed by the authentication methods that have been standardised for LDAPv3. A companion paper describes a directory application firewall
VIPS: simple, efficient, and scalable cache coherence
Directory-based cache coherence is the de-facto standard for scalable shared-memory multi/many-cores and significant effort is invested in reducing its overhead. However, directory area and complexity optimizations are often antithetical to each other.
This talk presents VIPS, a family of cache coherence protocols based on self-invalidation and self-downgrade. VIPS protocols remove the complexity and cost associated with directories in their entirety, thus increasing multiprocessors scalability, and at the same time, provide better performance and energy efficiency than traditional directory-based protocols
Buffalo Arts and Culture Organizations
Open Buffalo and Partnership for the Public Good collaboratively compiled a directory of organizations that promote social justice through locally based arts and cultural programmatic efforts. This directory has contact information, as well as the mission and social justice commitment of the various organizations
Important Lessons Derived from X.500 Case Studies
X.500 is a new and complex electronic directory technology, whose basic specification was first published as an international standard in 1988, with an enhanced revision in 1993. The technology is still unproven in many organisations. This paper presents case studies of 15 pioneering pilot and operational X.500 based directory services. The paper provides valuable insights into how organisations are coming to understand this new technology, are using X.500 for both traditional and novel directory based services, and consequently are deriving benefits from it. Important lessons that have been learnt by these X.500 pioneers are presented here, so that future organisations can benefit from their experiences. Factors critical to the success of implementing X.500 in an organisation are derived from the studies
Funding Resources for Women's Rights Organizations in the Middle East and North Africa
This directory of funders was compiled by AWID and the GFW, as a resource guide for women's rights organizations in the Middle East and North Africa. Please note that it is not a complete list, but a work in progress. Please note that by publishing this information AWID and GFW are not endorsing any of these as possible funders, but simply sharing information. The directory includes organizations that have confirmed their information and given permission to be included. If you have any changes to your organization's listing or any recommended additions, please contact Zawadi Nyong'o at [email protected]. The directory will be available for download on the AWID website at www.awid.org. Please feel free to disseminate this information widely with your partners in your country or region
Toward an Interactive Directory for Norfolk, Nebraska: 1899-1900
We describe steps toward an interactive directory for the town of Norfolk,
Nebraska for the years 1899 and 1900. This directory would extend the
traditional city directory by including a wider range of entities being
described, much richer information about the entities mentioned and linkages to
mentions of the entities in material such as digitized historical newspapers.
Such a directory would be useful to readers who browse the historical
newspapers by providing structured summaries of the entities mentioned. We
describe the occurrence of entities in two years of the Norfolk Weekly News,
focusing on several individuals to better understand the types of information
which can be gleaned from historical newspapers and other historical materials.
We also describe a prototype program which coordinates information about
entities from the traditional city directories, the federal census, and from
newspapers. We discuss the structured coding for these entities, noting that
richer coding would increasingly include descriptions of events and scenarios.
We propose that rich content about individuals and communities could eventually
be modeled with agents and woven into historical narratives
Report on the Second Catalog Interoperability Workshop
The events, resolutions, and recommendations of the Second Catalog Interoperability Workshop, held at JPL in January, 1988, are discussed. This workshop dealt with the issues of standardization and communication among directories, catalogs, and inventories in the earth and space science data management environment. The Directory Interchange Format, being constructed as a standard for the exchange of directory information among participating data systems, is discussed. Involvement in the Interoperability effort by NASA, NOAA, ISGS, and NSF is described, and plans for future interoperability considered. The NASA Master Directory prototype is presented and critiqued and options for additional capabilities debated
