This report documents EOSC EDEN ("Enhancing Digital preservation strategies at European and National level") Milestone 1.1 "Identification of Core Preservation Processes (CPPs) for WP2" by EOSC EDEN WP1 T1.2. A Core Preservation Process (CPP) is a specific action that every Trustworthy Digital Archive should undertake adequately - either directly or through its associated parties or services, in order to fulfill its digital preservation missions as evidenced in its preservation policy. The following assertions define the scope of CPPs: They focus on the operational activities required by digital preservation (understood as covering short- to long-term preservation) and do not cover strategic/managerial digital preservation activities nor the whole list of activities of a generic information management system, including secure IT infrastructures. Though digital preservation requires a deep knowledge of the properties, structure and possible uses of digital objects, which can be domain or discipline specific, the scope of CPP is limited to generic processes that take place in general when performing digital preservation regardless of specific content, domain or discipline. The list of CPPs and their description are established by a group of digital preservation practitioners. In addition, consensus within the digital preservation community about this list will be evidenced by references to prominent maturity models, self-assessment, and certification frameworks used by said community. CPPs are described as a sequence of implementable steps, either by humans or by automation.

We invite the community to provide feedback to the CPPs via the discussion forum available at https://github.com/EOSC-EDEN/wp1-cpp-descriptions/discussions
