Digital preservation policies

Ceres, Journal of Engineering, Technology, Agricultural Sciences and Sustainable Development ensures the intellectual content of electronic documents, for long periods of time, through digital preservation methods to safeguard digital resources, maintaining their attributes such as integrity, authenticity, unalterability, originality, reliability and accessibility.

The Publishing Entity Fundación Ediciones Clío guarantees the recording of the digital contents of the magazine and performs the copying of the same (rejuvenation) weekly, on internal servers and the hosting provider, through the Git control system, which allows storing an initial version of each file and keeping a record of the differences that may occur over time.

Additionally, the journal uses the services of Zenodo, a service that allows the Digital Object Identifier (DOI) to be assigned to each file, which facilitates the exchange, preservation and publication of data, under the guidelines of OpenAIRE. Data files and metadata are backed up nightly and replicated in multiple copies in the online system, ensuring that all metadata is stored internally in JSON format according to a defined JSON schema. It is exported in a variety of standard formats, such as MARCXML, Dublin Core and the DataCite metadata schema.

The preservation procedure is as follows:

Storage of digital content in formats such as Word, XML, HTML, PDF and tar.gz to ensure future conversions. Encapsulation of the information: verification of data consistency, migration and emulation. Self-documentation: information encoding. Self-sufficiency: minimization of system, data and documentation dependencies. OJS 3.3.0.20 allows the CLOCKSS system to store, preserve and distribute journal content through its publication manifest, available at:

Similarly, OJS includes the LOCKSS digital preservation system, in the Public Knowledge Project Preservation Network (PKP PNL) that also ensures the storage, preservation and distribution of journal content through its publication manifest and the Git Version Control System.
