Servicetypename Characterization service
Description Examination of digital objects (files) regarding criteria like file format identification, detection of protection measures in online publications, format validation, extracting technical metadata for digital preservation purposes. The service adresses the threats of the PARSE.Insight Roadmap 1_ how to understand or use the data and 2_ detection of access and use restrictions. It helps to sort out erroneous objects which may not be able to be presented in the future by format validation and it delivers valuable information for the representation information registry.

Automated IT web service using protocols like SOAP or REST.

Source The core of didigo was developed in the project dp4lib as a module in the koLibRI-toolkit.
Keywords format identification, validation, technical metadata
Scenario Without file format identification the archiving institution has no information what kinds of objects are archived. This information is essential to establish an efficient migration strategy. This is the only way to address the objects which are concerned by a format migration at all. Moreover, format validation helps to sort out erroneous objects which may not be presented in the future.

The service allow the detection of protected publications and report about the kind of the protection measure. Protected publications are likely to cause difficulties throughout the preservation process and access now and in the future. A password protected file is hard to convert in another format. Also the success of preservation actions by emulation is threatened.

Implementations didigo - DNB (internal service). DNB deliberates whether it can offer it as an external web service, too. Didigo uses mainly the File Information Tool Set (FITS).
Nextsteps The next step could be to wrap didigo with a WebService-Layer. By doing this, the service can be used externally.
