Counting California uses the U.S. Census Bureau's data dictionary for
processing of all U.S. Census studies. To make the
"Table (Matrix) Section" of the data dictionary easier to manage,
we
mark
up the
data
dictionary
with XML tags, and that's where the name
mudd
XML came from. The mudd XML only has tags for the data fields that are
found in the data dictionary. All mudd tags can be identified
by the attribute
source="producer".
It should be noted that since completing the original markup
of the U.S. Census Bureau's data dictionary, the metadata from other
studies has also been marked up. The mudd XML from these studies
was not derived from a data dictionary and,
therefore, may not have all of the same data fields.
Looking at the mudd XML, it was discovered that it didn't contain
all the data fields that are required for our processing.
The next logical step was to use the mudd XML as a foundation to
build
more than just
mudd
XML. This became the
momudd XML.
In addition to the mudd tags, momudd XML has data fields for concepts,
unit of measurement, and variables. All tags added to
the mudd XML to create the momudd XML are identified with the
attribute
source="cdl".
The concepts were added using the U.S. Census data dictionary subject
locator section, which was then manually scanned for accuracy.
The assigned concepts were taken from the set of existing
concepts in Counting California, not from the set of concepts used
by the U.S. Census Bureau. Therefore, if a person were to use
the concepts in Counting California's momudd XML, it would be at
the his/her own risk.
The unit of measurement is assigned based on the U.S. Census
general identification of table ids. The rules for making the
assignments are: any table, the id of which starts with 'P', will be
assigned 'individual' as the unit of measurement, and any table, the
id of which starts with 'H', will be assigned 'housing unit' as the unit
of measurement. The final step in this process involves manual
review of each table, with changes made as needed.
Counting California uses a very simple method for the generation
of the section of the table tagged with '<variables>'.
Because of its simplicity, it sometimes produces incorrect
results. Our algorithm splits the table's title any time
it encounters the word "BY". The algorithm gathers all the
sections produced by the splitting, and puts each one in the
'<variables>' section. An example title, for which the
algorithm produces correct results, is "SEX BY AGE".
In this case, there are two '<variables>' tags, SEX and AGE.
We understand that a high percentage of the '<variables>' values
are incorrect, but this is the first step toward the DDI.
The following studies have mudd and/or momudd XML. We will add
more here as we produce them. The mudd/momudd XML can be
downloaded or viewed via a browser.
