This table describes periods, which are groups of interfacial contexts believed to have been in use at the same time. This table contains inferences of parity between pairs of older: stratigraphically inferior context label (foreign key).younger: stratigraphically superior context label (foreign key).Itsįirst two columns refer to values from the label column of the This table includes observations of stratigraphic superposition. period: period identifier (foreign key).label: context identifier (primary key).This table describes the contexts identified by the archaeologist. Examples of each are provided in the hm git repository. There are seven data tables used as input to hm. Note that you might have to adjust the paths in roskams-cnf.csv to reflect your file structure. (hm-draw "path/to/examples/roskams-jumps/roskams-cnf.csv") This example from Figure 13 of Steve Roskams’ book, Excavation, was created with the following command: Sequence diagrams sometimes require “jumps” or “crossings”. The node coloring resolves potential ambiguities in the diagram.Īnother view of the complex H-structure with nodes colored according to reachability from Context 4. Note that you might have to adjust the paths in roskams-h-cnf.csv to reflect your file structure.Ī complex H-structure from an article by Irmela Herzog and Irwin Scollar, “A new graph theoretic oriented program for Harris Matrix analysis,” with nodes colored according to reachability from Context 2. (hm-draw "path/to/examples/roskams-h-structure/roskams-h-cnf.csv") “Avoiding a common error in Harris matrix construction,” is an example H-structure from Figure 14 of Steve Roskams’ book, Excavation. In this example, layer interfaces are recognized and the nodes are colored to reflect the relationship of Context 4 to other contexts in a Bayesian chronological model. In this example, the nodes are colored according to the directed graph concept of level.Īnother view of the stratigraphic section shown in Figure 12 of Edward Harris’ book, Principles of Archaeological Stratigraphy. Note that the symbol for a deposit is a box and for an interface a trapezium. The stratigraphic section shown in Figure 12 of Edward Harris’ book, Principles of Archaeological Stratigraphy. The hm package includes several example configuration and data files. Together, the configuration and data files can hold a complete description of site stratigraphy and its interpretation. The configuration information and the data are held in comma separated value files. The configuration file specifies paths to one or more data files and sets values for several dozen Graphviz dot variables. The hm package provides a single function, hm-draw, which expects a valid path to a configuration file as its sole argument. With the addition of a table of events, the hm package will produce a Bayesian chronological model. The hm package produces Graphviz dot source code for archaeological sequence diagrams from tables of stratigraphic observations, inferences, and interpretations. (hm-draw "path/to/configuration/file") Overview Installation with Quicklisp is recommended. The output file produced by the hm package is source code for Graphviz dot. It is convenient to install the software with the git distributed version control system. The hm package is Common Lisp software that runs on SBCL or Clozure CL.
