Additional fields in the Metadata

Besides deviceID, *startTime *and endTime tags, how can i add
additional fields in the Metadata as part of form submission ? I would for
example want to include the *version *and *formId *tags and bind them to
the data provided from the downloaded xform that contains the corresponding
tags. Any help would be appreciated.

The value of the version and formId are not accessible via any Javarosa
functions.

Note that these are automatically inserted into the submission whenever it
is saved, but are stored as attributes (version, id, respectively) of the
top-level XML element. So they are always present and tracked, but just
not as accessible form fields.

Within ODK Aggregate, if you click 'Display metadata', the version is
present as one of the metadata columns (as is the unique instanceID of that
data record).

So currently there isnt any way of adding additional metadata fields
besides the pre-defined ones? Would it be possible during form submission
to either POST some Name-Value pairs or even include an additional xml file
that would have additional custom metadata fields?

For metadata, you can use any of the predefined properties that can be
inserted into the form ( http://opendatakit.org/help/form-design/examples/
-- At the bottom of the page). And you can define any number of fields in a
form that have no question (with XLSForm, this may require hand-editing the
XForm .xml file after it is generated to remove the prompt). For example,
the instanceID field is a calculated field that has no user prompt (
http://opendatakit.org/help/form-design/ ).

Only the value and the top-level 'version' attribute
are specially treated and elevated to metadata status within ODK
Aggregate. The other metadata is needed for ODK Aggregate operations
(e.g., tracking what submissions still need to be published, whether or not
a submission is ready for publishing (marked as complete), and who
initially created and last modified a record, and the times of those
changes (useful for DB admins when recovering from database crashes or
restoring to a point prior to catastrophic human error in DB admin)).

Any other fields you insert would just appear as another column of data
from the form. By convention, we think of anything within a top-level

block as being metadata, but it is only a naming convention.
