Provides a web service (Python CGI) for dynamically presenting FGDC or ISO geospatial metadata from an XML file into HTML or plain text using XSLT transformations. More background info and many working examples available at http://pacioos.org/metadata/.

###Dependencies:
- Python
- Python libxml2 and libxslt modules: http://xmlsoft.org/xslt/python.html (e.g. ftp://xmlsoft.org/libxml2/python/libxml2-python-2.6.9.tar.gz)
###Set-Up Instructions:
- Copy get_metadata.py to your cgi-bin directory: e.g. /usr/local/apache/cgi-bin/
- Make sure get_metadata.py is executable: chmod 755 get_metadata.py
- Copy metadata.py to your Python module directory: e.g. /usr/local/lib/python2.7/site-packages/
- Configure get_metadata.py for your environment:
- WEB_BASE_DIR = '/usr/local/apache/htdocs'
- display_help_page() and die_nice(): modify HTML for your environment, replacing PacIOOS CSS stylesheet and SSI header/footer files with your own.
- Configure metadata.py for your environment. Assumes FGDC and ISO XML files
stored in "fgdc" and "iso" subdirectories of METADATA_DIR with filenames
equal to the dataset identifier (e.g. datsetid.xml):
- METADATA_DIR = '/usr/local/apache/htdocs/pacioos/metadata'
- XSLT_DIR = METADATA_DIR + '/xslt'
- Replace PacIOOS XSLT files with your own or modify ours for your environment,
replacing PacIOOS CSS stylesheet and SSI files with your own.
- pacioos-iso-html.xsl
- pacioos-fgdc-html.xsl
- Configure .htaccess for your environment. This allows the CGI script to be called from an alternative URL pattern such as (in our usage): http://pacioos/metadata/[datasetid].[html|xml|txt]. This file must reside in the top folder (e.g. "metadata" in the above example).
