Revision: 1

Contributors: Laurent Le Meur (EDRLab), Hadrien Gardeur (De Marque)

Requirements

LCP for PDF is based on the PDF Profile of the Readium Web Publication Manifest and follows its requirements for packaging.
Every LCP for PDF package must use:
- the .lcpdf extension.
- the application/pdf+lcp media type.
A numberOfPages property must be present in the metadata section of the manifest. It is used by Reading Systems to evaluate user’s progression in the publication.
PDF documents referenced in the readingOrder must not be compressed in the package.
A cover should be referenced in the resources section of the manifest and, if present, must not be encrypted.
An embedded LCP License Document must be located at license.lcpl.
Each encrypted PDF document must be accompanied by a type property must of value application/pdf.
Each encrypted PDF document must be accompanied by an encrypted element, where:
- scheme must be set to http://readium.org/2014/01/lcp.
- profile and algorithm must be set properly based on the LCP Encryption Profile of the License.
