PURL help What is a PURL? A PURL is a persistent URL, it provides a permanent address to access a resource on the web. When a user retrieves a PURL they will be redirected to the current location of the resource. When an author needs to move a page they can update the PURL to point to the new location.
Deep Web Search - A How-To Site Where to start a deep web search is easy. You hit Google.com and when you brick wall it, you go to scholar.google.com which is the academic database of Google. After you brick wall there, your true deep web search begins. You need to know something about your topic in order to choose the next tool. Persistent uniform resource locator - Wikipedia A persistent uniform resource locator (PURL) is a uniform resource locator (URL) (i.e., location-based uniform resource identifier or URI) that is used to redirect to the location of the requested web resource. PURLs redirect HTTP clients using HTTP status codes. PURLs are used to curate the URL resolution process, thus solving the problem of transitory URIs in location-based URI schemes like HTTP. Technically the string resolution on PURL is like SEF URL resolution. History[edit] The PURL concept was developed at OCLC (the Online Computer Library Center) in 1995 and implemented using a forked pre-1.0 release of Apache HTTP Server.[1] The software was modernized and extended in 2007 by Zepheira under contract to OCLC and the official website moved to (the 'Z' came from the Zepheira name and was used to differentiate the PURL open-source software site from the PURL resolver operated by OCLC).
White Paper: The Deep Web: Surfacing Hidden Value This White Paper is a version of the one on the BrightPlanet site. Although it is designed as a marketing tool for a program "for existing Web portals that need to provide targeted, comprehensive information to their site visitors," its insight into the structure of the Web makes it worthwhile reading for all those involved in e-publishing. —J.A.T. Searching on the Internet today can be compared to dragging a net across the surface of the ocean.
Handle System - Wikipedia As with handles used elsewhere in computing, Handle System handles are opaque, and encode no information about the underlying resource, being bound only to metadata regarding the resource. Consequently, the handles are not rendered invalid by changes to the metadata. The system was developed by Bob Kahn at the Corporation for National Research Initiatives (CNRI). The original work was funded by the Defense Advanced Research Projects Agency (DARPA) between 1992 and 1996, as part a wider framework for distributed digital object services,[2] and was thus contemporaneous with the early deployment of the World Wide Web, with similar goals. The Handle System was first implemented in autumn 1994, and was administered and operated by CNRI until December 2015, when a new "multi-primary administrator" (MPA) mode of operation was introduced. Thousands of handle services are currently running.
The Ultimate Guide to the Invisible Web Search engines are, in a sense, the heartbeat of the internet; “Googling” has become a part of everyday speech and is even recognized by Merriam-Webster as a grammatically correct verb. It’s a common misconception, however, that Googling a search term will reveal every site out there that addresses your search. Typical search engines like Google, Yahoo, or Bing actually access only a tiny fraction — estimated at 0.03% — of the internet. The sites that traditional searches yield are part of what’s known as the Surface Web, which is comprised of indexed pages that a search engine’s web crawlers are programmed to retrieve. Institutional repository software comparison The Guidelines to compare Institutional Repository Software have been published as part of UNESCO’s Open Access Strategy. The publication compares the features of the major platforms and is intended to help libraries focus on which features will help facilitate the success of their repository. Institutional Repositories (IRs) were first developed as an online solution for collecting, preserving, and disseminating the scholarship of universities, colleges, and other research institutions.
News aggregator - Wikipedia Function[edit] Visiting many separate websites frequently to find out if content on the site has been updated can take a long time. Aggregation technology helps to consolidate many websites into one page that can show the new or updated information from many sites. Aggregators reduce the time and effort needed to regularly check websites for updates, creating a unique information space or personal newspaper.
Institutional Repositories Institutional Repositories (IRs) can be directly loaded into EBSCO Discovery Serviceso that they can be fully searched alongside all other EDS resources/content. Loading Institutional Repositories EBSCO supports harvesting institutional repositories via Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) or via File Transfer Protocol (FTP). EBSCO has developed a flexible framework for mapping your data to EDS.
