Organizing A Century of Data Continued from page 21 access. This gives Barrick the flexibility to let everyone know a dataset exists. When the metadata is added to the catalog, it will show up in search results. However, it restricts data access to the group most likely to need it. If others want access, they must contact the persons listed under the Responsible Party metadata attribute and make their case. For example, Barrick’s land managers want people to know whenever there is land data available for their search area, but they do not want people to have access to that data without consulting a land professional. This procedure ensures that anyone using the data is made aware of any confidentiality or area of interest agreements associated with the land polygon. Future By tagging its huge store of geologic information with metadata, Barrick has taken a significant first step in increasing the value of this data. Future work will include incorporating spatial data stored in other repositories, such as acQuire from acQuire Technology Solutions for geochemical and drilling data and EQuIS from Esri business partner EarthSoft for environmental data. Barrick will also serve data from the SDI to other applications. For example, for vehicle tracking applications, Web services from the SDI data provide context for vehicle movement. In the first step in publishing data with MXD Publisher, all datasets are listed and checked for valid and complete metadata. SDE Publisher publishes the file geodatabase from the MXD Repository to the SDE Repository. 22 ArcUser Summer 2010 www.esri.com
