OJAX Federated Search Service Software

An exciting announcement about OJAX, an open-source federated search tool.
OJAX federated search service software is now in Beta release and available for download. Version 0.7 has improved performance, stability and user feedback, as well as additional features such as RSS/Atom feed support. (Atom feeds of stored searches alert users when new content matching their interests is harvested.)

OJAX illustrates how federated search services can respond to new user expectations generated by Web 2.0:

  • Rich, dynamic user experience. OJAX uses Ajax technology to provide immediate dynamic response to user input.
  • Intuitive interface. The OJAX interface provides the simplicity and familiarity of Google but with the power of advanced search
  • Integration, interoperability and reuse. OJAX uses loosely coupled Web Services and supports the OpenSearch RSS standard, thus facilitating integration with a range of virtual library environments, institutional repositories, course management systems and institutional portals.
  • Open source standards-compliance. OJAX supports best-practice open source standards and software, including OpenSearch, OAI-PMH, StAX and Apache Lucene.
Features of OJAX:
  • Auto-completion of search terms
  • Triggering of auto-searches
  • Dynamically scrollable search results - no more navigating between pages
  • Auto-expansion of search result details
  • Rapid sorting of results
  • Integrated with the Firefox 2 / IE 7 search feature
  • Supports OpenSearch Discovery
  • Stored searches as Atom feeds
  • Includes an OAI-PMH harvester
  • Easy to install in your own institution
Further information, demo and download.

Two alternative packages are available:

  1. OJAX GUI, Web Services & Harvester
  2. OJAX GUI, Web Services, Harvester & example repository index

WebDAV

I'm wondering why Web-based Distributed Authoring and Versioning (WebDAV) is not more common. It seems pretty simple and has MS support, yet I never have heard of it being used. Or am I just missing it?
The WebDAV protocol's aim was to make the World Wide Web a readable and writable medium, in line with Tim Berners-Lee's original vision. It provides functionality to create, change and move documents on a remote server (typically a web server or "web share"). This is useful, among other things, for authoring the documents which a web server serves, but can also be used for general web-based file storage that can be accessed from anywhere. Important features in WebDAV protocol include locking (overwrite prevention), properties (creation, removal, and querying of information about author, modified date, etc.), name space management (ability to copy and move Web pages within a server's namespace) and collections (creation, removal, and listing of resources). Most modern operating systems provide built-in support for WebDAV. With the right client and a fast network, it can be almost as easy to use files on a WebDAV server as those stored in local directories.

Call to Koha Users

LibLime, the support company for Koha, posted this announcement:
The Koha project is working to improve Koha's visibility by adding Koha users to an important automation list. This list is maintained by Marshall Breeding (U.S. researcher), and tracks libraries worldwide and what ILS they are using. Marshall puts out a library technology guide every year (this year's is upcoming) which is very influential in helping libraries select an automation system.

Traditionally, Koha has not been included in his guide, and we are trying to change that this year :) In fact, Marshall has specifically invited Koha users to include themselves in the guide, to ensure open-source automation gets the recognition it deserves. We've been encouraging Koha users to add information about themselves to the site, and adding libraries ourselves as we come across them.

If your library is using Koha, make sure you are counted! To make sure your library has already been added to Marshall Breeding's list, you can do a search for your library.

If your library is not listed, you can add yourself.

You'll need to add your library by the end of the month to be counted for this year's guide.

PURL Spam

The spam problem on the OCLC PURL server has been resolved.
A new PURL server has been put into service.

Deleting what we though were spam. We added a disclaimer about PURLS on the first page.

53674 PURLS were deleted along with 95 user ids.

PURLS has now change, to request a user id you will need to request it from the System Administrator (me for now).

Users that have an existing USER ID should be able to create PURLS, DOMAIN, GROUPS etc.

Don't know if I got all we think we're spam, but if any are found let me know, also any USER ID that should not have been deleted and was, let me know.

Link Evaluator

Link Evaluator is a free Firefox add-on from OCLC.
Link Evaluator is a Firefox extension designed to help users evaluate the availability of online resources linked to from a given Web page. When started, it automatically follows all links on the current page, and assesses the responses of each URL (link).

Link Evaluator examines both the HTTP status code and the page contents returned by each URL.
