Installing Catalog Services for Web (CSW) - ISO Metadata Profile

To install the CSW ISO extension:

1. Visit the GeoServer download page and navigate to the download page for the version of GeoServer your are using. If you do not have the CSW extension yet, get it first. Both the csw and csw-iso downloads are listed under extensions. The file needed are geoserver-*-csw-plugin.zip (if necessary) and geoserver-*-SNAPSHOT-csw-iso-plugin.zip, where * matches the version number of GeoServer you are using.
2. Extract these zip files and place all the JARs in WEB-INF/lib.
3. Perform any configuration required by your servlet container, and then restart.
4. Verify that the CSW module was installed correctly by going to the Welcome page of the Web administration interface and seeing that CSW is listed in the Service Capabilities list. Open the CSW capabilities and search for the text gmd:MD_Metadata to verify that the ISO metadata profile was installed correctly.
