The journal Divulgaciones Matemáticas adopts a digital preservation policy that guarantees access to digital files, through a management process that maintains their long-term availability, which guarantees access to files even when formats and technologies evolve. To this purpose, we use the plataform Zenodo.org and a set of activities has been designed to keep this preservation process up-to-date and active, through:

1. Evaluation of the preservation value: It is carried out through the training and awareness of the personnel involved in the preservation process.

2. Identification: A code system is used to maintain the organization and privacy of the stored information.

3. Verification of the integrity: A periodic review is carried out to verify the integrity of the stored documentation.

4. Content classification: The content is classified according to pre-established patterns.

5. Assurance of sustainability: The digital preservation policy includes mechanisms that guarantee the sustainability of the stored documentation over time.

6. Adding metadata: The information to be preserved is packed together with descriptive metadata.

Among the mechanisms of the journal's digital preservation policy are:

Hardware

• Use of virtual servers and services to make optimal use of existing hardware and guarantee expected performance.

• Availability of high-performance professional servers, equipped with redundant systems in storage devices and located in different geographical locations.

Software

• Policies defined for updating the journal's platform.

• Use of operating systems and software-based applications.

• Constant updating of operating systems and applications.

• Strict policies for safekeeping systems.

• Use of defined and software-based text editors.
