[GeoNetwork-users] GeoNetwork 2.1.0 alpha-1

GeoNetwork GeoNetwork User

Hi all,

from the project page you can download the first alpha of geonetwork 2.1.
After installing it, remember to use the 'admin'/'admin' as username and
password because what you provide in the installer gets discarded (we
started to refactor the installer).

here is a list of what is new:

- Added Lucene FuzzyQuery support
- Added catalogue services for the web 2.0.1
- Added ISO19115 CSW 2.0.1 output stylesheets (thanks to Steven Smolders/Stefaan Desender)
- Added RSS search services
- Added chinese localization (thanks to Enri Zhou)
- Added log4j to both jeeves and geonetwork
- Logs moved into jetty/log folder. Now old logs are archived

- Added web/WEB-INF/db/data.tgz. This is an empty McKoi database ready for use,
  very usefull to users that do a cvs checkout/update: simply unpack where it is.

- Added localization of categories, groups, regions, operations and profiles
- Added an Ajax wen interface to configure harvesting
- Removed uuid-2.1.0.jar: used java 1.5 builtin UUID class
- Removed jaxen: used java 1.5 classes
- Increased connection pool to 10 connection to allow harvesting tasks
- Added more information to users (email, address, organisation etc...)

- Fixed the metadata-util.xsl stylesheet so that GeoNetwork can run on Java 1.6
  (thanks to Andrew Davie)

- Added 'author' to the RoleCd codelist
- Harvesting engine totally rewritten to provide more flexibility

- Now the search engine works with Chinese language (thanks to Enri Zhou)

- Fixed bug with user list: if the user is an Administrator but with id other
  than 1 only a subset of the groups where shown

- Fixed bug with thumbnails stylesheet: now the 'back' button is correctly
  shown

- Fixed validation bug when adding a new metadata

- Fixed problem with IPv6 protocol: geonetwork was unable to handle the
  0:0:0:0:0:0:0:1 local address.

- Fixed a security hole: using sql injection was possible to login into geonetwork
- Fixed "Services is not a subcontext" exception with Z39.50
- Added reconnection patch for MySQL (thanks to Enri Zhou)
- Fixed a security hole in user management : a user admin could gain admin privileges

Some notes:

- the iso 19139 can be viewed but not edited

- the new harvesting interface works but the server is not completed so now
  you cannot harvest from anywhere

- the CSW has some problem that we fixed after having created/tested the jar file

We have planned to release a new alpha in November (first or second week) with
some more bugs fixed and a few other advances.

Cheers,
Andrea

Hi Stefan,

Ciao Andrea,

Thanks for the good release news. I perhaps should really test GeoNetwork.

* I'm always interested in webcrawlers/harvesters: What does the Harvester
do? Any documentation about its strategy and algorithm? bread first?
respecting robots.txt?

Geonetwork will support several harvesting protocols. Harvesting means that
you connect to a remote node, import some metadata and keep them synchronized
as they change remotely. This operation is periodic.

Up to now there is a standard geonetwork harvesting (you harvest from another
geonetwork node) and there will be a web folder harvesting (to define, maybe a
web-dav interface should be used). There will be even a OAI-PMH protocol planned
by the end of this year.

I'm also writing some docs so these new features will be documented.

* What is "RSS search services"? is this an implementation of OpenSearch
spec. or do you mean to get search results from GeoNetwork as RSS?

These are XML services that can be called by clients and that provide output
in RSS format.

* Given you have something like a RSS search service implemented, I think
it's a small thing to implement OAI-PMH, at least given the minimal
implementation I described here
http://wiki.osgeo.org/index.php/Geodata_Metadata_Requirements#Guidelines_for_a_minimal_OAI-PMH_implementation

In your case you could simply adopt the Java component
harvester2-0.1.10.zip<http://pubserv.oclc.org/oaiharvester2/jars/dist/harvester2-0.1.10.zip&gt;
which
can be downloaded from
http://www.oclc.org/research/software/oai/harvester2.htm . There is a test
out of the box on Linux/Unix (% sh test.sh) and Windows (% test.bat).

-- Stefan

I will look at that.

Cheers,
Andrea
