Botanical Resources: Corn

Part of the Dolores Archaeological Program project

Year: 1985

Summary

The corn dataset was used in association with an intensive botanical study designed to identify different varieties of corn in the assemblage of corn cobs and plant fragments recovered in the course of DAP fieldwork. The variables in this dataset contain information and measurements pertaining to the number or rows of kernels on an ear, its shape and size, and various details about glumes, cupules, and kernels.

Variables for the CORN10 dataset have been described by Wilshusen et al. (1999); see especially the section "Botanical resources" by Joel Tyberg in chapter 3. In most cases, his descriptions are suitable for use as metadata and have been repeated almost verbatim here. See also chapter 7, "Resource Studies," by Kenneth Lee Petersen in the Final Synthetic Report. Selected resources from the collection of published and unpublished DAP reports may have been used for clarification in some cases and will be appropriately referenced.

mpn Modeling period.
VARCHAR  Uncoded Value Macrobotanical none none
spn Classifies the type of subphases that a record may belong to.
VARCHAR  Uncoded Value Macrobotanical none none
csiteid The Anasazi Heritage Center has given each specimen three unique codes, including csiteid, to facilitate management of their DAP collections. This value denotes the entry's corresponding Smithsonian site number.
VARCHAR  Uncoded Value Provenience and Context : Horizontal Location none none
avgwidth The average width of a collection.
BIGINT  Uncoded Value Macrobotanical none none
stco To obtain a full site designation for any entry, append the Smithsonian site number to this variable.
VARCHAR  Uncoded Value Provenience and Context : Horizontal Location none none
shape The shape of the cob; tapered, straight, etc.
VARCHAR  Uncoded Value Macrobotanical none none
pl The point location variable is a subdivision of the field specimen number that denotes an item or group of items of a significant type and/or context.
VARCHAR  Uncoded Value Provenience and Context : Context none none
pattern Records any pattern that the cupules present.
VARCHAR  Uncoded Value Macrobotanical none none
part DAP analysts selected from 32 possible values when describing the parts of a plant represented by each record.
VARCHAR  Uncoded Value Macrobotanical : Other none none
charred This variable indicates the degree of charring on a specimen, if present.
VARCHAR  Uncoded Value Macrobotanical : Other none none
kernel Denotes whether or not there are actual kernels present on a cob.
VARCHAR  Uncoded Value Macrobotanical none none
cobjectid The Anasazi Heritage Center has given each specimen three unique codes, including cobjectid, to facilitate management of their DAP collections. Since this value is used in association with the AHC ARGUS database for tracking the location of a record, it is important for any researcher requesting objects from the curator.
VARCHAR  Uncoded Value Lookup : Code none none
xsect The shape of a cross section of cob; flattened, round, etc.
VARCHAR  Uncoded Value Macrobotanical none none
cdept The Anasazi Heritage Center has given each specimen three unique codes, including cdept, to facilitate management of their DAP collections. This value specifies the tool department to which each record belongs.
VARCHAR  Uncoded Value Lookup : Code none none
caccnid The Anasazi Heritage Center has given each specimen three unique codes, including caccnid, to facilitate management of their DAP collections. The first digits of this value indicate the year that it was accessioned.
DOUBLE  Uncoded Value Lookup : Code none none
avgthick The average thickness of a collection.
BIGINT  Uncoded Value Macrobotanical none none
avgleng The average length of a collection.
BIGINT  Uncoded Value Macrobotanical none none
site Site number refers only to the sequential position of a site within a single Smithsonian state and county designation. To obtain a full site number for any entry, this value must be appended to the Smithsonian state and county designation.
BIGINT  Uncoded Value Provenience and Context : Horizontal Location none none
erosion The amount of erosion; classified as partial, complete, or no erosion.
VARCHAR  Uncoded Value Macrobotanical none none
wholdiam The entire diameter of a cob, measured in millimeters.

length The length of a cob, measured in millimeters.
BIGINT  Uncoded Value Macrobotanical none none
glumwdth The width of glume, measured in millimeters.
BIGINT  Uncoded Value Macrobotanical none none
fs The most basic type of provenience data recorded for all information obtained during DAP fieldwork is the field specimen number. These values are sequentially assigned to unique vertical and horizontal locations within each site.
BIGINT  Uncoded Value Provenience and Context : Context none none
complete1 The completeness of a record---whether a record is complete or fragmentary.
BIGINT  Uncoded Value uncategorized none none
catno A unique catalog item number used by DAP analysts, for identification in the laboratory.
BIGINT  Uncoded Value Lookup : Code none none
estimate The estimated number of kernels on an ear of corn when the actual number cannot be determined.
BIGINT  Uncoded Value Macrobotanical none none
diameter The diameter of a cob, measured in millimeters.
BIGINT  Uncoded Value Macrobotanical none none

BIGINT  Uncoded Value Macrobotanical none none
cultnum A number assigned to define a specific cultigen type.
BIGINT  Uncoded Value Macrobotanical none none
actual The actual number of rows of kernels on a specific ear of corn.
