Extracta Mathematicae has the purpose of preserving digitally in the long term all the documents it houses. To do this, we are developing an action plan that includes basic measures to ensure the digital durability of scientific material:
  • Backups Storage of documentation on servers and external storage units
  • Converting formats to more secure ones
  • Periodic checks of the integrity of files to avoid corruption
  • Monitoring the environment technology to anticipate possible migrations of obsolete formats or software
  • Digital preservation metadata
  • Use of DOI in your new materials

For the purpose of digital preservation, E.M. stores all the documents in easily readable formats (such as PDF). In the event that it would not be possible to maintain the usability of all existing formats, the journal ensures the return of the files to their authors. The digital preservation policy will be reviewed annually by the magazine.
