metaf2xml can download, parse, and decode aviation routine weather reports (METAR, SPECI, SAO), aerodrome forecasts (TAF), synoptic observations (SYNOP), and BUOY observations, and store the data as XML. XSLT style sheets convert it to plain language, as HTML or text. Current weather data from NOAA and other sources can be fetched and displayed.
Search::Xapian is a Perl XS frontend to the Xapian C++ search library. It is a fairly complete wrapper: most features of the Xapian library are made available for use from Perl. Xapian is a highly adaptable toolkit that allows developers to easily add advanced indexing and search facilities to their own applications. It supports the Probabilistic Information Retrieval model as well as a rich set of boolean query operators. It's fast and scalable to hundreds of millions of documents.
Wiaflos Accounting is an attempt to create a multi-platform server-client based accounting system. The goal is to have a central accounting engine which can either run on a dedicated server or on the same PC as the client interface. A SOAP API allows for the easy writing of GUI or Web interfaces or for tying into in-house systems. It is intended to be useful for everyone from single-person organizations to multinational corporate entities.
The DBIx::Perlish module provides the ability to work with databases supported by the DBI module using Perl's own syntax for the four most common operations: SELECT, UPDATE, DELETE, and INSERT. By using DBIx::Perlish, you can write most of your database queries using a domain-specific language with Perl syntax. However, the module is not intended to replace all use of SQL in your program. The DBIx::Perlish module quite intentionally neither implements nor cares about database administration tasks like schema design and management.
