Export data

The software allows exporting the S.U. sheets, the excavation journal and a Harris' matrix file.

Stratigraphic units can be exported in two formats:
- HTML: it's a formatted sheet, suitable for inclusion "as is" in reports and scientific documents.
- txt: unformatted text file where data of each S.U. are listed in two column (attribute-value). Ideally, this is a format more suitable for further computer analysis, although I.L.I.U.M. does not offer any facility in this sense.

Once created, the files are stored in the same folder of the intervention, and named by the intervention name followed by the extension ".HTML" or ".txt".

Excavation journal can be exported in HTML. Only journal entries classified as "public" will be exported.

Once created, the files are stored in the same folder of the intervention, and named by the intervention name plus the postfix "_journal" followed by the extension ".HTML" or ".txt".
Please do not confuse the file [excavation name]_journal.html with the file [excavation name].ilium-journal The latter is a file created automatically by Android at the time of creating the excavation.
It represents temporary data used by the excavation database file and and it does not concern the user.

The Harris' matrix1 of the stratigraphic units can be stored in a ".dot" file. The latter is a plain text file that is a standard for rendering "flow" or "network" graphs, hence it's suitable for the stratigraphic matrix. The file is saved in the same folder of the intervention, and named by the intervention name followed by the extension ".dot".
It can be opened and rendered to a graphic format (.svg, .png, .pdf ...) by Graphviz, an open source graph visualization software.2

Also, several online tools can be used for visualizing .dot flowcharts. Some of them require the user "manually" opens the .dot file with a text editor, copies/pastes it to into a text area of the site, and finally manually saves the generated image (right click on the image -> Save as).
A more versatile online tool is GraphvizFiddle (https://stamm-wilbrandt.de/GraphvizFiddle/#), that allows to load your own file (the one exported by ILIUM), to generate the graph and to download it as .svg graphic.
