LLA ZPortal
This document provides an overview of library portals and federated search engines, including definitions, major developers, standards, and LAU's implementation of the ZPortal system. It discusses terminology, differences between portals and federated search engines, examples of popular systems, and advantages and disadvantages of the portal approach. The case study focuses on LAU being the first academic institution in Lebanon to adopt ZPortal and how it functions to allow single-search access to the library catalog and other resources.

Link Resolver A link resolver uses the OpenURL standard to create links to content, such as E-journals, library catalogs, Internet search engines, some ILL systems, bookshops, etc. In other words, when a patron finds a citation or reference to a specific article, this link resolver supplies the best available path to the content, anywhere in the library collection.

Editor's Notes
- #10 Note that each bullet needs a click to appear on screen!! OpenLinking is FD’s OpenURL resolver. The OpenURL resolver takes metadata and matches it with locally held rules about where your electronic content is available from. It means that FDI have implemented the OpenURL standard in its draft form, to enable your users to link from a search result in ZPORTAL to digital conent. Not all content providers and e-journal sites you use will be OpenURL enabled. However, this does not mean that you cannot link to those sites. FD have developed a range of templates which specify the metadata required for a website. Content can mean a range of media - including journals, electronic full-text, the library catalog, Internet search engines and so on.
- #18 Note that individual mouse clicks are needed on this slide. Life before ZPORTAL and OpenLinking - the research process currently goes something like this - your users search a database or databases to find articles that may be useful for their term paper they find some useful records and then print them out or save them to a floppy they then go check the OPAC and find the item on the library shelves or go to the e-journal (if they can find it on your website or through the OPAC perhaps) they would then locate the volume and then the issue (in both e-journals and on the shelves) in the case of e-journals, they may then find that the library doesn’t have a subscription, or they aren’t allowed access but if they are lucky , then they may finally reach their destination - the article
- #20 This slide is on page “x” of your training manual as well as in the ppt slides. So what’s going on in the background? The user must be authenticated to use openlinking - this enables authorization to take place - does the user have appropriate access rights? From a search result, metadata is taken and passed to the OpenURL resolver - configurable rules are questions - can I find the ISSN? What services are available to this user? And how do I build the URL to that service, given the metadata I have from the search result? Following this provess, the user is offered a number of links and by following the links, they can access full-text or library catalogues.
- #24 OpenLinking is the final piece in the ZPORTAL jigsaw. Using openlinking you will be resolving “the most appropriate copy” issue. OpenLinking is FD’s solution for linking from a citation to the full-text or other appropriate website or service.
