Greenstone 2.71 release notes:
------------------------------

New Windows, GNU/Linux, Mac OS/X and Source distributions available:
Greenstone v2.71

The Windows, GNU/Linux, Mac OS/X and Source distributions of Greenstone
v2.71
are now available for download from our sourceforge page:
http://sourceforge.net/projects/greenstone, or via http://www.greenstone.org

This release is a "feature" release which means it contains a lot of new
functionality, some of which may be a bit flaky. Unless you are using
Greenstone in a production environment, we encourage you to upgrade and
report any bugs found so the next release will be a stable one. It is
also a
lot easier for us to help you if you are using the latest release.

New features and changes include, in no particular order:

GLI:
-----
- new Format panel, containing all options relating to collection
formatting.
These options don't require a rebuild to take effect. Preview Collection
button now also on this Format panel.
- default indexer for new collections is MGPP
- searchtypes now a format statement instead of a design option.
- new Macros section on Format panel - can edit collection's extra.dm
directly.
- redesign of Search Indexes section of Design panel.
- Search indexes now displays options for stem, casefolding and
accentfolding
(MG and MGPP only). If selected, the appropriate index will be built.
Search preferences for these options will depend on the appropriate index
being built.
- new Search section in Format panel: can edit display text for search form
drop down lists (indexes, subcollections, levels etc)
- metadata set management now on Enrich panel (Manage Metadata Sets
button).
- New collections default to using the Dublin Core metadata set, and no set
prompt is given. This can be changed from the Enrich panel.
- updated help text
- now restarts itself if a new language is selected.
- plugins.dat and classifiers.dat no longer used. Plugin and Classifier
information is dynamically loaded when needed.

GEMS:
-----------
- reimplementation to make a simpler interface
- only one set is now open at a time
- A predefined set of attributes for set/element is provided
- Is launched from GLI to create a new metadata set or edit an existing one

Collection Exporting:
------------------------
- File->Export in GLI. Now supports exporting as Greenstone Archive (GA),
DSpace batch import, Greenstone METS, and MARCXML formats.
- All export types support the use of XSLT to transform resulting XML
files.
For example, could export to GA format, then transform to a custom format
using an XSLT file

Export to CDROM:
------------------
- now has a -noinstall option, so that the resulting CDROM doesn't install
anything onto the host computer

MGPP:
------
- maxnumeric support added
- query term truncation (e.g. comput*) with casefolding fixed for non-ascii
query terms
- accent folding support added (thanks to Juan Grigera): Generates a
new index which folds accents, in the same way that case folding
works. Accent folding means that □ will match e, and vice versa.
This is turned on by the user via the preferences page.
- Mongolian unicode support

MG:
----
- Mongolian unicode support

Lucene:
--------
- upgraded to version 2.0.0
- now supports return of search term frequencies, and search term
highlighting
- user will be notified if stop words were included in the query
- search result sorting by metadata: search results can be sorted
by any metadata that an index was built on.
- Improvements thanks to DL Consulting

Plugins:
----------
- ConvertToPlug: -keep_original_filename option. Original file will be
saved
using original name rather than doc.pdf, doc.doc etc.
- ISISPlug: - "^*" values for each field extracted, which contain the first
subfield value.
- Logically deleted records are now ignored
- CSVPlug: - processes comma separated value files. The first line is a
list of metadata names and subsequent lines, one per record, contain the
values. A new document will be created for each record.
- MetadataCSVPlug - processes comma separated files as above. Requires a
filename field which contains the file name of the document to which the
record metadata will be assigned.
- HTMLPlug - new -extract_style option. If set, will extract any style
information from the HTML head tag (style, script, link) and store it
as ex.DocumentHeader metadata.

Collection Building Options:
-----------------------------
- -sortmeta option to import.pl now takes a comma separated list of
metadata
- -OIDmetadata option to import.pl: if -OIDtype is 'assigned', then
-OIDmetadata indicates which metadata element holds the identifiers,
rather than always using dc.Identifier

Incremental Building:
----------------------
- GLI supports a 'minimal rebuild', which is not incremental building.
There are two stages to collection building, importing and building, and
one or both of these may be suppressed.
- If minimal rebuild is selected: importing will only be carried out if
documents have been added/removed, metadata has been edited, or plugins
have changed. Building will only be carried out if design options
have changed. If nothing in the collection has changed (apart from
formatting), then clicking Build Collection will do nothing.

- Command line building supports incremental addition of documents.
- -incremental option to import.pl will only import files that have a newer
timestamp than the archives.inf file in the archives directory.
- -incremental option to buildcol.pl is only supported for Lucene
collections.
The archives.inf file will indicate which archives have been previously
built, and only new ones will be indexed. The GDBM database is recreated
without needing to re-read all the old archives. If you no longer have
your
initial building directory, then use the '-builddir index' to index the
new documents into the current index.

Depositor:
--------------

- New Institutional Repository style web based interface used for adding
documents and metadata into an existing collection.
- Interface customisable using macro files
- Collection design not handled by this interface.
- Enable it by setting 'depositor enabled' in etc/main.cfg
- Will use incremental import, and incremental building for Lucene
collections

Metadata Database Exploding:
-----------------------------
- can now obtain multiple documents for a record (and assign the
metadata to
each one)
- new -records_per_folder option, which explodes the records into multiple
subfolders. This can speed up metadata editing in the GLI.
- Refer and BibTex files now explode.

Downloading:
-------------
- Downloading files/records via HTTP, FTP, Z3950, SRW, OAI now
supported, via
the modified Download panel in GLI

Searching:
-----------
- tidied up parsing of the fielded search form (mgpp and lucene) -
behaviour
of an individual field in the form is the same as a single line search
- simple and advanced modes consistent between single line and fielded
searching
- pressing enter in a fielded search form now submits the form.
- search preferences reorganised - hopefully easier to understand
- more help text, particularly for advanced and fielded searching
- casefold, stemming and accentfold preferences now dependent on collection
design

Metadata and Formatting:
--------------------------
- Date metadata and DateList now accept yyyy-mm-dd as well as yyyymmdd
format.
- [Date] and [Language] now display the raw value. [format:Date] and
[format:Language] display the formatted values. For example,
Date=20010204: [Date] => 20010204 [format:Date] => 4 February 2001
Language=fr: [Language] => fr [format:Language] => French
- This formatting uses macros (_iso639:iso639xx_ macros in languages.dm,
and
in base.dm) so is customisable.
- new Greenstone metadata set, greenstone.mds, namespace 'gs'. Contains
metadata elements that are special to Greenstone, and can be edited.
Currently, there is only one element: gs.DocumentHeader. If set, the
value will be used for the macro
- macro used in HTML head tag in document
display.
Set by the receptionist to the value of gs.DocumentHeader or
ex.DocumentHeader. This allows documents to use individual style
information
such as CSS stylesheets.
