# Extra Data Types

Up to now, you have been using common data types, like:

* `int`
* `float`
* `str`
* `bool`

But you can also use more complex data types.

And you will still have the same features as seen up to now:

* Great editor support.
* Data conversion from incoming requests.
* Data conversion for response data.
* Data validation.
* Automatic annotation and documentation.

## Other data types

                }
                this.endDate = null;
                this.setStartDate(date.clone());
            } else if (!this.endDate && date.isBefore(this.startDate)) {
                //special case: clicking the same date for start/end,
                //but the time of the end date is before the start date

        Metadata source = createMetadataFromArtifact(artifact);
        Date date = new Date();
        addSnapshotVersion(target.getVersioning(), date, artifact);
        SnapshotVersion sv1 = addSnapshotVersion(source.getVersioning(), date, artifact);
        // although nothing has changed merge returns true, as the last modified date is equal
        // TODO: improve merge here?
        assertTrue(target.merge(source));
