For the development since Summer 2003 see
| 0.9.0 June 2003 |
The simple standalone server ois is provided,
currently single-threaded and non-windows only.
Run in the database directory, naming the databases to serve like
/opt/openisis/sto/ois cds unesb anotherdb
For a demo of query and read access, see php/query.
Other calls are now added to the Isis/Db.php and a like
plain perl module will follow soon.
Note, that the communications protocol probably is to undergo some
changes on the way to version 1.0, however,
the only interesting features still missing in this version are
so you may get by with this version for a fairly long time ...
- unicode collation support (which you might not need)
- views based indexing (but application based indexing is supported)
- new-style metadata (typically ignored in applications anyway)
| 0.8.9 May 2003 |
passes all test. It's typically more than 10% smaller than the traditional,
has the same format on all platforms and no limits on field or record size.
It can be fixed with a text editor; the pointer file is rebuild automatically.
By default, it uses 4/3/1 pointers (4GB DB size, 16MB records).
for how and when it's used. Create a text db using
sto/openisis -db db/cds/cds >db/cds/cds.txt
New plain PHP package features flexible "v" operator,
direct access to the plaintext database (using 4/4/0 pointers)
and isis database server access.
The OpenIsis Tcl server oits can be used like
bin/oits -db 1234 test/testsrv.tcl
a plain server is to follow soon ...
| 0.8.8 April 2003 |
Sort of a preview to stable version 0.9.
The C-API seems to be mostly stable now (but don't use the RecStream),
and there are not much known bugs (deleting index entries is broken;
fixed in current CVS version).
Yet, of course, features are going to be added ...
The Tcl-API now gives a good idea of what it's going to be,
but still will undergo some changes during the following month.
After that has settled down, Java, Perl and PHP will receive their upgrades.
Although there may be some changes until version 0.9,
it's recommended to start playing around with the Tk demo GUI, tisis,
and it's formatting TSPs (Tcl Server Pages),
that also can be used as CGIs (see demo.cgi).
this little test database
(a copy of CDS recoded to Latin-1, with OpenIsis index and
a procedure to select index entries).
Also try dexml, which uses the TclXML package to convert *ANY*
valid XML input to ISIS records w/o loosing information!
| 0.8.7.5 April 2003 |
Last version of the 0.8.7.x developer series.
It contains all the developments of winter 03.
Version 0.8.7.5 is the last to contain all that devel stuff.
Version 0.8.8 will have explicit passing of Session removed,
i.e. change the 0.8.7.x API, but still be compatible for the 0.8.6 calls.
| Perl improvements February 2003 |
Try 'make pdemo' to see encoding support (Cp850 to Latin1,
for other see perl/encoding.pl), a sample standalone perl install tree,
support for 'indicators' (initial unnamed subfields)
and a non-nonsense way of spitting out XML.
| 0.8.7.4 January 2003 |
Experimental FDT support and preliminary (old-style),
but pretty usable Tcl bindung by Matthias included
(see tcl/test for how it works,
please contact us before using it for serious work).
Of course several fixes...
| 0.8.7.2/3 December 2002 |
No longer uses stdio but direct threadsafe buffered io (*snprintf still used).
Every session has their own buffered in, out and err streams,
which may be accessed w/o interlocking.
| 0.8.7.1 November 2002 |
The IO module is rewritten to use native windows calls for WIN32.
This also fixes some problems with read-only databases.
Error checking needs to be added; however, under wine,
it passes the standard test.
adjust make.mingw to fit your MINGW installation, then use
make WIN32=sigh test
| October 19th 2002 |
The OpenIsis society ("Verein") has been founded with 15 members.
Chairman is Erik Grziwotz, other board members are Gabi Rohmann,
Ingo Struck and Thomas Sonnemann.
| 0.8.7 October 2002 |
Version 0.8.7 supports writing of DOS/WinIsis masterfiles and xrf.
This currently works fine for a single process on Linux. See
writing.txt for details. Current TODOs: interlock multiprocess
writing (PHP, Perl CGI) and fix the windows and solaris versions.
Besides writing support, there is a new streaming record reader,
which groks various formats like the SYSPAR.PAR, email headers and
property files, so you can fill your db from such textfiles. Next
step: new indexing engine.
| August 2002 |
No new software yet. Still very busy doing metawork. We are
preparing to set up an organisation to support OpenIsis
development with much more momentum and a company for professional
services like help on large scale ISIS installations. paperwork on
the universal ISIS record
| July 2002 |
some paperwork on What is it about ISIS that makes it ISIS?
| 0.8.6 June 2002 |
This version supports basic formatting. While most, especially
graphical, features of WinISIS or CISIS formatting are not yet
supported (which are typically not used in a web environment
anyway), there is support for repeated subfields as declared by
MARC for many fields. See formatting notes for details. The
perl binding supports formatting (see the test.pl), enhanced
versions for all those languages are to follow soon.
| PHP June 2002 |
Braulio Josť Solano Rojas from Costa Rica created a PHP
binding, which can be seen in action at galileo. Available as
download or from sourceforge module php-openisis. Also, the
Institut Teknologi Bandung of Indonesia switched it's web
index to a PHP/OpenIsis based version.
| 0.8.5.2 March 2002 |
Much enhanced PERL binding. See the OpenIsis.pm included in the
| 0.8.5.1 March 2002 |
Java now has support for basic formatting modes like MHL, various
HTML-safety modes (like escaping all non-ASCIIs), a
Vn-field-selector-style method and several nice utils.
Indentation is not properly handled, since there is no easy common
solution in HTML. Will build tools for a choice of standard
strategies later ...
| 0.8.5 March 2002 |
Finally some implementation of the query language (demo). All
the operators are there (including /(tag), but not /(t1,t2...)).
Every attempt is made to limit the potential costs of even
extremely stupid queries like "$"^"$", so no historical (#n) or
intermediate results (for precedence) are stored. Queries are
processed strictly left to right on a buffer of 1000 hits.
| 0.8.4 January 2002 |
Nearly complete rewrite of search code with support for NEAR
conditions. Fixed alignment problems in IFP, now works with the
unesb db (-format aligned) and the cds db as distributed with
The cds db we had with previous versions (from an old CDS
distribution) has a mixed format: aligned leaf files, others
unaligned. Although support for a mixed format is easily achieved
with openisis, it will not be included unless somebody has a need
for it (send us mail).
The JSP demo now supports searching the unesb db with over
58.000 rows (note the hosting server is a 500MHz Celeron).
Searching is limited to 1000 postings, usually resulting in a
somewhat lower number of rows (where rows have multiple matching
postings). The lowest row number (MFN) that was cut off is
recorded, and it is possible (not yet in the JSP) to repeat the
search starting from that rowid.
| 0.8.3 October 2001 |
First truly usable release, since we have true search by index now
(as prefix or complete word). Search gives a list (array) of
sorted MFNs; arithmetic on those lists (and, or, not) is
straightforward. The JSP demo shows how a query is refined
(narrowed) iteratively by ANDing it with a second query. And
thanks to Veronica Lencinas and colleagues, we have a version of
this document en espanol.
| September 2001 |
Not a new release yet, but maintenance and testing. New structure
logging mechanism. Sources are available via CVS at
sourceforge. Windows version openisis.exe running.
| 0.8.2 August 2001 |
openisis now under LGPL, no legacy code. Conversion from file
structures governed by abstract dynamic description rather than
C-structs, so we can support different file layouts, much larger
databases, big endian processors and more. Simple full-scan search
available in C-Lib and Java. Given a random read throughput of
about 30.000 Records/sec on a lame 300 MHz Notebook this seems to
be of practic use. jsp demo under development ;).
| 0.8.1 June 2001 |
Java native interface version available. Java package org.openisis
has Db, Rec, Field, Test. NativeDb implemented in libopenjsis.so.
Subfield splitting and htmlifying in pure java.
| 0.8.0 May 2001 |
Subfield splitting and htmlifying. Everything also available from
perl as an xsub. Record shows up as hash, handy but no repeated
fields. Makefile.PL, test.pl etc.
| 0.7.9 May 2001 |
First version: static C-Library libopenisis.a for reading records
by rowid(Mfn). Executable "openisis" does test. Logging,
argumentparsing, Makefile, demo etc.
