## title: Catch-all Data Repository Introduction (Legacy)

The [Catch-all Data Repository](https://datarepo.eosc.cz) is a repository for general scientific data. This temporary documentation describes the running legacy version of the repository, a new documentation is under construction as the system will undergo a major overhaul.

## Mission

The repository is intended for general scientific data that should be
stored into a repository, but for which no better
deposition option exists. While the catch-all repository is handled with
all the care needed to operate a repository, users are advised to

* prefer using an established topical repository is available for their
  data in their scientific discipline,
* get familiar with their scientific community standards and customs in
  their particular field of study.

Specific community repositories will usually provide better findability of
the data and have specific metadata models tailored for the needs of
particular communities. You can also check the [recommendations to choose a
repository](../../intro-to-nrp/use-cases#choice-of-a-repository).

If you are positive that no better choice than the catch-all repository is
available for you, then welcome to the catch-all repository. Make sure to get familiar with its basic principles and limitations.

## General Information

TL;DR what you need to know:

* the Data Catch-all Repository is operated by CESNET in scope of the NRP project

* users of the national e-infrastructure (i.e. staff and students of public universities, the Academy of Sciences and other research organisations) and their direct collaborators may depose data there

* [generic metadata model CCMM](https://github.com/techlib/CCMM) covering basic needs is supported (similar to a bibliographic record)

* [persistent identifiers (DOI)](https://www.doi.org/) can be assigned

* the records in the repository are published by default; an embargo period
  may be set: data of embargoed records are kept private and after the period
  elapses, the record is automatically published in full

* supported dataset licenses are variants of Creative Commons

* metadata is publicly available and completely free to use

* there are no restriction on file formats, files can be zipped

* published data is accessible to the public internet (without any
  user authentication)

* after the record is finalised, its data cannot be changed any more, a new version of the record must be created should changing the data be necessary; metadata, though, can be corrected any time

* data deletion is handled upon user request by user support

* for the time being, there is no data life cycle policy yet. Note that it is the policy of organisations assigning persistent identifiers (e.g. DOI) that at least a basic metadata record of a dataset must be preserved forever, even if the data itself is deleted.

## Terms of Service

The repository is operated under the National Repository Platform.
