Update October 5, 2006
The development group at Arizona Hyrdologic Information System (AHIS) has installed a Meta-Door system and provided the following helpful installation notes
If you do setup an independent Meta-Door installation, we'd appreciate if you could give credit (maybe a link back to the Meta-Door twiki homepage http://nautilus.baruch.sc.edu/twiki_carocoops/bin/view/Metadoor/WebHome
) somewhere on your website and a notice by email to jcothran[at]asg.sc.edu so that we can help coordinate possible updates or funding needs.
The below are some comments by the developer Bashar who works with AHIS:
We made quite a few changes to metadoor, and now itís fully integrated with AHIS (You can check it here: http://18.104.22.168:8084/AHIS/
. You need to create yourself an account first and then click on Manage my metadata). Thanks to use of Tiles changing the layout and content was pretty easy!
I didnít write any more documentation after the last document I sent. Building and running Metadoor can be a bit tricky; I really suggest using Maven instead of ant to better manage Metadoor.
One issue I didnít like about metadoor is the use of postgre dump tool to generate SQL scripts. It generates a lot of postgre-specific code that works only with Postgre which locks you into only using postgre database with metadoor. Another issue I didnít like is mapping xml elements to relational tables. This is really a complicated process that is very hard to scale and maintain. I would have preferred keeping the xml elements in their native binary format (in xml files) and read/write to the xml files directly. This would greatly simplify the design of the database and makes adding support to more elements a whole lot easier.
Other than that the source code was pretty clean and easy to understand. Thanks for sharing such a good project.
Sourceforge File Download
Update April 27, 2006:
The available source code which has been provided at sourceforge and elsewhere is a very old version - contact jcothran[at]asg.sc.edu if you are looking for the most recent files.
A download of a zipped package of source code files is available at
An online viewable sourceforge CVS for Meta-Door is located at
Notes on Sourceforge CVS usage can be found at
Note that for sourceforge commands, the project name is 'osioss' the module name is 'meta-door2' and the user name will either be the developer name or 'anonymous'.
#for all cvs steps set the CVS_RSH environment variable
#if prompted for anonymous password, press enter
cvs -d:pserver:email@example.com:/cvsroot/osioss login
#to download entire meta-door module
cvs -z3 -d:ext:firstname.lastname@example.org:/cvsroot/osioss co -P meta-door2
WinCVS settings for download and updates. For developers, substitute the developer name for 'anonymous'
Note: In the process of moving production boxes, the materials currently available don't quite cover what's completely needed. I'm in the process of adding and documenting these remaining elements.
Support Code Versions
The paths listed for the downloaded files would live under the tomcat webapps directory similar to
Environment arguments which will be specific to your environment are located in the following files and should be changed accordingly
The application assumes that mp (metadata parser install package at http://geology.usgs.gov/tools/metadata/all_win.exe
) has been installed under the default option of C:\USGS
And the files currently used to configure and run mp at
assume the CATALINA_HOME environment variable is defined as C:\jakarta-tomcat-5.5.5 and should be checked and changed as needed to match the environment setup
Run 'ant all' from webapps\meta-door2 initially and after any change to the database tables.
For a PostgreSQL?
GUI database interface we use and I'd recommend EMS detailed more at the following link
Coordinating development efforts
The initial application has been developed using Java/Struts/Hibernate running against a PostgreSQL?
relational database(although the SQL code should be non-database specific).
For developers who wish to suggest fixes or added features that work within the above framework, the following is suggested:
- notify jcothran[at]asg.sc.edu of the development ideas in case something is already in the works
- make and test your changes locally
- submit changes to jcothran[at]asg.sc.edu for testing and incorporation into the sourceforge cvs
For further development, the underlying table schemas could also be used for development towards other non-Java specific interfaces(php,etc) or a variety of xml schema exports.
For developers wishing to branch outside of this framework(say using the same database, but supplying command line exports or interfaces using perl, php, python, etc), the same above steps would apply, but a different sub-version of Meta-Door may end up being created supporting specific functionalities.
Used the following perl script
and mp config
file to clean up xml files so they are passed through mp successfully generating all the other format outputs.
