Once a care flow has some steps and forms in it, go through the
[data catalog](/docs/data/data-catalog) and check that the data points are consistent and used as
intended before publishing.

## Each data point shows its source, key and type [#each-data-point-shows-its-source-key-and-type]

Open a data point to see those details.

## Flag personally identifiable data while building, not afterward [#flag-personally-identifiable-data-while-building-not-afterward]

Mark a data point as **personally identifiable information**, or PII.

The flag governs how that data is handled downstream, so set it when the data point is created rather
than after the data has already flowed onward.

## Add metadata while the meaning is still fresh [#add-metadata-while-the-meaning-is-still-fresh]

Attach metadata to captured data points, so the meaning travels with the value. A data point named
`score_2` with no metadata can't be interpreted by whoever analyzes it a year later.

## Export the catalog for people who don't work in Studio [#export-the-catalog-for-people-who-dont-work-in-studio]

Copy the export out of the catalog to review a whole care flow's data with someone who doesn't use
Studio, or to hand an analyst the field list before they write queries.

## Next steps [#next-steps]

**Next:** [Source Control](/docs/data/source-control) for versioning the care flow itself.
