|Catalog:- http://www.nongnu.org/catalog/ Open Source (900 KB tar).
Catalog is a perl program that allows to create, maintain and display Yahoo! like directories. The user interface is 100% HTML. It requires a MySQL database to run. The general idea behind the design of Catalog is that creating a catalog is mainly a matter of organizing objects in a structured tree. For Catalog, the objects are records in a table of the SQL database. The structured tree is a set of tree nodes and relations between these nodes. The maintainer of the catalog is in charge of building the tree and placing objects in this tree.
Catalog makes no assumption about the data contained in the records. It is not designed specifically to build a catalog of URLs, despite the fact that we mainly use it to classify URLs. It can be used to classify companies, bug reports and so on. Special care has been taken to allow easy customization of a catalog, from the programmer point of view and from the HTML page designer point of view. Although the program structure is not documented at present, the choice of simple perl object orientation should ease the specialization for specific purposes. The HTML display is completely controlled by a set of template files. The template files structure has been kept as simple as possible so that only minimal comprehension is necessary from the HTML page designer. In particular it behaves well with page composer tools like Dreamweaver or PageMill. The features of the software are: -
Display structured trees of resources.
Display chronologically ordered resources and associated calendar.
Display alphabetical indexes of resources.
Allow full text search in the resources and the category names.
Powerful HTML based administration of catalogs.
On-Line editing of resource records.
Handle an arbitrary number of catalogs.
High performances using mod_perl and Apache.
Easy customization of the user view using HTML template files.
It is possible to define more than one view of the same catalog.
Load and unload a thematic catalog in XML.
Create an HTML dump of a structured tree to publish a static version.
Complete documentation including a guide and a reference manual.
Ready to use examples.
A detailed documentation of the software is also available.
Site of the Week:- http://www.pubsub.com/
PubSub is a matching service that instantly notifies you when new content is created that matches your query. Using a proprietary Matching Engine, PubSub is able to read millions of data sources on your behalf and notify you instantly whenever a match is made. PubSub’s Internet-scale matching engine is a “prospective” search tool that complements traditional “retrospective” search engines. PubSub’s prospective search matches user requests against new documents as they’re published—in real time, all the time. Traditional search stores data and then allows to find documents within that store of data. PubSub operates by first storing subscription query, and then watching for new information that matches it. Query will be checked against every piece of new information passing through their Matching Engine. It is the Internet’s most comprehensive blog-monitoring service tracking more than 6.5 million Weblogs as well as 50,000 USENET newsgroups, all SEC/EDGAR filings, press releases from major wire services, and FAA airport delay alerts. The PubSub service is compatible with any information delivery system that can be accessed from the Internet - including email, SMS, PDA/mobile devices and Instant Messaging networks - allowing to select where, when, and how you want to receive your information. PubSub’s RSS and ATOM feeds are compatible with Web-based news aggregators like Bloglines and My Yahoo! as well as desktop aggregators like NewsGator, FeedDemon, and Gush. One can also download Pubsub sidebar available for Internet Explorer and Firefox, so there will be no need to visit the website to check the new results of defined query. It will automatically display new results in the sidebar that matches with our query. This free service will be very useful for the information professionals who have to monitor the news items about their company/competitive company as well as for current happening in their areas of interest.
That's all for this week. See you next week.
