The development team for the NSF-sponsored Knowledge Network for
Biocomplexity project has released new versions of their open-source
data management software for ecology. The Morpho 1.1.0 and Metacat
1.1.0 releases include bug fixes and some new features in each of the
packages. See the README in the releases for more details.
Morpho is a data management application for managing ecological data.
Morpho allows researchers to describe their data using a comprehensive
and flexible metadata specification, and to share their data publicly or
to specific collaborators over the Knowledge Network for Biocomplexity
system. It works fully on Windows, MacOS X, Linux, and other platforms
(untested).
Metacat is a flexible metadata catalog for metadata and data. It
implements a database storage system for XML formatted documents and
allows storage metadata and data with arbitrary schemas. Thus it
supports a wide variety of metadata standards. Metacat supports several
databases on the back-end, including Oracle, PostgeSQL and SQL Server,
and has been run on various Linux, UNIX, and Windows platforms. The
server supports document storage, retrievel, query, validation, and
transformation into HTML (using the XSLT stylesheet language). In
addition, there is a mechanism for replicating the database to other
metacat instances for backup and load balancing purposes. Metacat
currently uses an LDAP database for authenticating users, but was
written to accomodate other authentication services as well.
Metacat is currently being used to implement the KNB network, the
Organization of Biological Field Stations Data Registry, the UC Natural
Reserve System Data Registry, and the MARINE Data Registry.
Both software packages are freely available (including source code) from
the KNB website:
http://knb.ecoinformatics.org
under the "Software" section of the site.
We welcome participation in the design and development of these packages
(see the KNB web site for details).
