[Incubator] The Open Data Cube as a OSGeo Community Project

[Jody Garnett]

Yeah this kind of thing can be quick (many projects keep track of code from
day one) or take years (for geoserver we eventually sat down with a code
sprint and git history).

Here is a script I made, that produced a CSV file, that I then open up in a
spreadsheet:

#!/bin/bash
for file in `git ls-files -x src/*`
do
    HASH=`git log --diff-filter=A --format="%H" -- $file | tail -n 1`
    AUTHOR=`git show -s --format="%aN" --date=short $HASH --`
    CREATED=`git show -s --format="%cd" --date=short $HASH --`
    MODIFIED=`git log --format="%cd" --date=short -n 1 -- $file`
    printf "%s,%s,%s,%s,%s\n" $file "$AUTHOR" "${CREATED:0:4}"
"${MODIFIED:0:4}" $HASH
done

Keep in mind some of the fun of this exercise is to double check where your
code actually came from and confirm you have permission to distribute it as
open source. While a script can provide a running start, it is your
confidence in what you have done as a team that we are really going for
here :)

Also note that code providence audits like this are performed when
evaluating software projects for use. Performing this check yourself lowers
the bar for organizations wishing to use your software.
