Formal metadata: information and software
Date: Wed, 24 Jan 2001 16:05:14 -0500 Subject: mp-users: new tool for dbf files mp-users, I just wrote up version 1 of a small utility called DBFmeta. This tool is designed to take a DBF file and generate from it a snippet headed by Detailed_Description that you can paste into metadata using Tkme or by some other process. The useful things it does are Set up structure for each attribute Determine type of each attribute For string variables, create Enumerated_Domain for each distinct value, alphabetized. For integer variables with fewer than about 20 distinct values, creates an Enumerated_Domain for each distinct value, sorted. For integer variables with more than about 20 distinct values, creates a Range_Domain. If the values include only one or two negative values, those negative values are described separately as Enumerated_Domain (for example, where -99 means "no data"). For double variables, creates a Range_Domain. In this case it doesn't do the trick with negative values, though. Includes the ESRI extensions Attribute_Type, Attribute_Width, and Attribute_Precision. These can be left out using -strict. In an interactive mode, asks you for the definitions of the attributes, the units of the numbers, and the resolution of double variables. It doesn't ask about definitions of Enumerated Domain Values because there are too many of them. Use an editor such as Tkme to add that information. What it doesn't do is what it can't find out on its own: the definitions of the attributes, their units, the meanings of the Enumerated_Domain_Values, measurement resolution. There's a new web page for this at <http://geology.usgs.gov/tools/metadata/tools/doc/dbfmeta.html> I have just included it in the current packages. I invite you to give it a try. Please let me know if you encounter unexpected behavior. Please let me know if I can provide additional information or assistance.

The changes include at least one bug fix that you'll want if you were trying out version 1.0. So it's up to version 1.2 now, and I've rebuilt the Windows packages to include it. There's also a direct link to the .exe file on the dbfmeta web page.
