Digital Locker is a key initiative under Digital India program. It aims at eliminating the use of physical documents and enables sharing of verified electronic documents across agencies. Digital Locker provides a dedicated personal storage space of 1GB in the cloud to citizens. It will enable various organizations registered on Digital Locker to push certificates of citizens directly in their Digital Locker in electronic format. Citizens can also upload and securely store the scanned copies of legacy documents in Digital Locker. These legacy documents can be electronically signed using eSign facility. A citizen can share these electronic certificates online with various departments and agencies registered on Digital Locker while applying for the services provided by them. Thus, Digital Locker brings the citizens, issuers and requestors on one platform. DigiLocker accepts and provides documents in two formats, PDF and XML. The PDF documents are provided to citizens in their DigiLocker account whereas the XML format is used as a machine readable version of a document to be used by the programs to take decision based on specific data in the document. Since DigiLocker accepts certificates from many issuers, it is necessary to standardize the format of these certificates so that the consumer can conveniently use a single certificate format irrespective of the issuer. This document provides the XML structure of mostly commonly used certificates in DigiLocker.
