GCIDE is the GNU Project's publication of CIDE, the Collaborative International Dictionary of English. It is a freely-available set of ASCII files containing the marked-up text of a substantial English dictionary. (130,633 headwords and growing!)
From the introduction to each GCIDE file:
This dictionary was derived from the Webster's Revised Unabridged Dictionary Version published 1913 by the C. & G. Merriam Co. Springfield, Mass. Under the direction of Noah Porter, D.D., LL.D. and from WordNet, a semantic network created by the Cognitive Science Department of Princeton University under the direction of Prof. George Miller and is being updated and supplemented by an open coalition of volunteer collaborators from around the world. This electronic dictionary is the starting point for an ongoing project to develop a modern on-line comprehensive encyclopedic dictionary, by the efforts of all individuals willing to help build a large and freely available knowledge base. Contributions of data, time, and effort are requested from any person willing to assist creation of a comprehensive and organized knowledge base for free access on the internet. Anyone willing to assist in any way in constructing such a knowledge base should contact: Patrick Cassidy email@example.com 735 Belvidere Ave. Office: (908)668-5252 Plainfield, NJ 07062 (908) 561-3416

Version 0.46 of GCIDE can be obtained from the GNU FTP site. It uses a markup notation that is almost, but not quite, XML. I figured it would be more useful as a well-formed XML document, so I undertook the conversion. The result is GCIDE_XML. It's possible that, at some point in the future, GCIDE itself will be published in XML, at which point this website will become redundant.
If you're wondering what the tags mean, see GCIDE's tagset.web file.
Thanks to Alexei Puzikov for submitting a nice little Perl script to perform a headword search. (I might never have gotten around to writing one on my own.)
Perl-style regular expressions are permitted.
For example, a query of
will (in a few seconds) return entries for
among many others.
If the first character of the query is not a letter
(i.e., it's a regexp metacharacter),
the search will take significantly longer,
since it will scan all files.
.etch will return entries for
but it will take about a minute.
The "root file" of the XML document is
gcide.xml (36 kb).
It declares and references the following files as SYSTEM entities:
authorities 284 kb abbreviations 40 kb A 3620 kb B 3092 kb C 5404 kb D 3292 kb E 2244 kb F 2396 kb G 1756 kb H 2048 kb I 2332 kb J 492 kb K 456 kb L 1964 kb M 2908 kb N 1036 kb O 1376 kb P 4548 kb Q 312 kb R 2620 kb S 6188 kb T 2920 kb U 944 kb V 944 kb W 1536 kb X 48 kb Y 184 kb Z 140 kb

each "letter" file is an external general parsed entity.
section 4.3.2 of the XML specification.)
If you give a letter file to an XML processor that expects a document entity,
it will rightfully report that the file's content is not well-formed.
For instance, Internet Explorer 5 will complain that
"only one top level element is allowed in an XML document".
Other XML processors might (also) report violation of the
now contains a complete DTD for the document.
Formerly, it only declared character and external entities;
now it includes element type declarations
and attribute-list declarations.
Please note that the element type declarations
have been generated from the existing document,
and thus are somewhat inelegant.
