What funding is there | Funded by EU | None | ||
How high is the risk of the service getting terminated | No risk | Low risk | Low risk | |
Data | Withdrawal | If the uploaded research object must later be withdrawn, the reason for the withdrawal will be indicated on a tombstone page, which will henceforth be served in its place. Withdrawal is considered an exceptional action, which normally should be requested and fully justified by the original uploader. In any other circumstance reasonable attempts will be made to contact the original uploader to obtain consent. The DOI and the URL of the original object are retained. | Easy to delete a private file, but almost impossible to delete a published file | |
Revocation of DOIs | Content not considered to fall under the scope of the repository will be removed and associated DOIs issued by Zenodo revoked. User access may be revoked on violation of Terms of Use. | |||
| Encryption | No | Yes | Yes |
Virus check | Yes | |||
| Storage of sensitive data | In so far that the data can be closed for access data are secure, so for instance social security numbers cannot be read by everyone | Launched in November 2015 Confidential files – Enables new collaboration opportunities by releasing a metadata-only record for files which are commercially or personally sensitive | Data can be selected to be viewable to only a number of people, so data are secure |
Policy/law | Access | Open for all, but users must specify a license for all publicly available files. Licenses for closed access files may be specified in the description field. | ||
| Mandate | Government | Commercial | Institutional | |
| Preservation | Retention period | Items will be retained for at least 20 years | Minimum of 10 years. | |
Functional preservation | Zenodo makes no promises of usability and understandability of deposited objects over time. | Planning to allow data consumers to download the files in original formats | ||
File preservation | Data files and metadata are backed up nightly and replicated into multiple copies in the online system. | Data files and metadata are backed up nightly and replicated into multiple copies in the online system. | ||
Fixity and authenticity | All data files are stored along with a MD5 checksum of the file content. | All data files are stored along with a MD5 checksum of the file content. | ||
| Curation | Yes | No | No | |
Metadata | Access and reuse | All metadata is exported via OAI-PMH and can be harvested. All metadata is stored internally in MARC according to the schema defined in Zenodo metadata. Metadata is exported in several standard formats such as MARCXML, Dublin Core, and DataCite Metadata Schema according to OpenAIRE Guidelines. | ||
License | Metadata are licensed under CC0, except for email addresses. | |||
Digital preservation requirement
| ||||
INGEST
M – must
S – should
C – could | Requirement | |||
S | The digital archive will enable us to store administrative information relating to the Submission Information Package (SIP) (information and correspondence relating to receipt of the SIP). | The uploaded data is archived as a Submission Information Package | None | |
S | The digital archive will include a means for recording appraisal decisions relating to the Submission Information Package and individual elements within it. | Yes | ||
M | The digital archive will be able to identify and characterise data objects (where appropriate tools exist). | DOI | DOI | DOI |
S | The digital archive will be able to validate files (where appropriate tools exist). | All data files are stored along with a MD5 checksum of the file content | ||
S | The digital archive will support automated extraction of metadata from files. | Upcoming feature: Metadata extraction | ||
S | The digital archive will virus check files on ingest. | No | ||
C | The digital archive will be able to record the presence and location of related physical material. | |||
S | It will be possible to select and configure the required level of automation within the ingest workflow. | |||
M | The digital archive will be able to process large numbers of files and files that are large in size. | Large number of files that each are max. 10GB (soon to be 1TB) | ||
DATA MANAGEMENT | ||||
M | The digital archive will generate persistent, unique internal identifiers. | DOI | DOI | DOI |
M | The digital archive will ensure that Preservation Description Information (PDI) is persistently associated with the relevant content information. The relationship between a file and its metadata/documentation must be permanent. | No | ||
M | The digital archive will support the PREMIS metadata schema and use it to store preservation metadata. | No | ||
S | The digital archive will enable us to describe data at different levels of granularity – for example metadata may be attached to a collection, a group of files or an individual file. | Yes - in end of 2015 | ||
M | The digital archive will accurately record and maintain relationships between different representations of a file (for example, from submitted originals to dissemination and preservation versions that will be created over time). | |||
M | The digital archive will store technical metadata extracted from files (for example that which is created as part of the ingest process). | |||
| M | The digital archive will fulfill Dublin Core metadata | Yes | ||
| M | The digital archive will guarantee long-term preservation and integrity of the data | Yes | ||
| M | The digital archive will be certified to the Trusted Repositories Audit and Certification standard | Will be in 2016 | ||
| M | The digital archive will have access controls that can be used to restrict access to sensitive data if this is necessary | Yes | ||
PRESERVATION PLANNING | ||||
M | The digital archive will allow preservation plans (such as file migration/normalisation) to be enacted on individual or groups of files. | |||
C | Automated checking of significant properties of files will be carried out post-migration to ensure these properties are adequately preserved (where appropriate tools exist). | |||
M | The digital archive will record actions, migrations and administrative processes that occur whilst the digital objects are contained within the digital archive. | |||
ADMINISTRATION | ||||
M | The digital archive will allow for disposal of data where appropriate. | |||
S | A record must be kept of data disposal including what was disposed of, when it was disposed of and reasons for disposal. | |||
S | The digital archive will have reporting capabilities so statistics can be collated. For example it would be useful to be able to report on numbers of files, types of files, size of files, preservation actions carried out. | |||
ARCHIVAL STORAGE | ||||
M | The digital archive will actively monitor the integrity of digital objects on a regular and automated schedule with the use of checksums. | Yes | ||
M | Where problems of data loss or corruption occur, The digital archive will have a reporting/notification system to prompt appropriate action. | Yes | ||
S | The digital archive will be able to connect to, and support a range of storage systems | |||
