Raptor is the RDF Parser Toolkit for Redland and currently consists of two
parsers: RDF/XML and N-Triples. Raptor is designed to integrate closely
with Redland and also work entirely standalone, in which case it will use
simple internal routines to perform the functions.
Rarian is designed to be a replacement for scrollkeeper. It is
currently undergoing heavy development. As of writing, rarian can be
installed in place of scrollkeeper and everything will work okay.
Rarian manages documentation metadata (as specified by the Open Source
Metadata Framework (OMF) and provides a simple API to allow help browsers
to find, sort, and search the document catalog. It will also be able to
communicate with catalog servers on the Net to search for documents which
are not on the local system.
Rasqal is a free software / Open Source C library that handles Resource
Description Framework (RDF) query syntaxes, query construction and query
execution returning result bindings. The supported query languages are
SPARQL and RDQL.
The re_graph.pl program graphs regular expressions. The guts of the regular
expression engine is a simple state machine. The various states and
operations in the regular expression parser can be displayed using a
surprisingly simple diagram.
A few notes on what you are looking at:
* The nodes Start and Stop denote the beginning and end of the regular
expression.
* The solid squares denote atoms. Lines indicate the next state. When a
line splits, the state machine will take the top line first. If it's
path is blocked it will backup and take the next lower line. This is
repeated until it finds a path to the end or all paths are exhausted.
* Brown boxes indicate a grouping operation, i.e. ().
* Green boxes indicate a zero with test. The state machine will perform
the test inside the box before moving ahead.
Redet allows the user to construct regular expressions and test them against
input data by executing any of a variety of search programs, editors, and
programming languages that make use of regular expressions. When a suitable
regular expression has been constructed it may be saved to a file. redet stands
for Regular Expression Development and Execution Tool. For each program, a
palette showing the available regular expression syntax is provided. Selections
from the palette may be copied to the regular expression window with a mouse
click. Users may add their own definitions to the palette via their
initialization file. Redet also keeps a list of the regular expressions
executed, from which entries may be copied back into the regular expression
under construction. The history list is saved to a file and restored on
startup, so it persists across sessions. So long as the underlying program
supports Unicode, redet allows UTF-8 Unicode in both test data and regular
expressions
Redland is a library that provides a high-level interface for RDF
allowing the model to be stored, queried and manipulated. This
package provides a number of bindings for various languages for
the Redland library.
RefDB is a client-server database system for storing, retrieving and
formatting bibliographic references.
This is a variant of the Flex fast lexical scanner. Flex was written
in the early 1990s by Verne Paxson. This version has been modified
by Thomas Dickey, so that it conforms to ANSI C. It includes other
improvements, but remains compatible with Paxson's 2.5.4 release
(as well as POSIX lex). See the NEWS file for details.
ReplaceIt was written as a quick, light and effective replacement to
the combination of sed/awk/grep/head/tail and other such shell
utilities, as well as being quicker in startup (at least) than an
equivilant Perl solution.
