Descriptive metadata
Descriptive metadata is recorded in the digital long-term archiving system with the aim of uniquely describing and identifying the objects. The descriptive metadata is intended to ensure the long-term assignment of the content of the object and is created by the relevant TIB specialist teams, delivered directly to the long-term archiving team by the data producers or collected by the long-term archiving team from various data sources. Descriptive metadata in the DC section of ie.xml (see Specifications for archival information packages (AIPs) must be available as Dublin Core. This metadata is indexed. Various metadata standards (MARC, Dublin Core, MODS, EAD, NISO, MIX and others) can be integrated into the source MD section of ie.xml.
There are currently several methods for recording descriptive metadata:
- enrichment with metadata from the union catalog K10plus
- the collection of Dublin Core metadata supplied via the OAI interface from the institutional repository of Leibniz Universität Hannover
- the capture of supplied Dublin Core metadata in the dc section of ie.xml
- the collection of supplied metadata from source systems as source metadata in ie.xml
Additional catalogue systems may be connected as required.
Enrichment with metadata from the union catalogue K10plus
Librarians collect metadata on the objects according to the RDA cataloguing standard. Older catalogue records are available based on the RAK-WB standard.
CMS enrichment is conducted during the transition from operational to permanent archival storage. CMS enrichment involves querying metadata via the SRU interface of the Gemeinsamer Verbundkatalog and mapping the output to Dublin Core. Mapping governs the assignment of PICA+(only in german) fields to the relevant Dublin Core qualified elements, as well as the scope, structure and content of the descriptive metadata.
The metadata are written to a separate catalogue.xml and given an identifier; the identifier is written to the ie.xml. The metadata from the catalogue.xml are indexed.

Identifying metadata
Identifiers used
Internal-system identifiers at the object level
Rosetta creates and allocates various internal-system identifiers.
Identifier for objects: system internal identifier generated by Rosetta to identify IEs, representations, files and packets during deposit and SIP processing.
Event type identifier: Rosetta-defined ID for an event category (see Event).
Identifier for processes: ID assigned by Rosetta for executed processes, for example a Preservation Action (see Administrative metadata and Logging of preservation actions).
Rights identifier: the ID of a policy, for example, a configured usage right (see ), a retention policy, or a delivery license.
Identifier for agents: the ID of an agent in the sense of PREMIS, for example, a producer, a plug-in, a connected system, or a user.
The internal-system identifiers are unique and permanent within the system.
If new policies or processes are defined by a user, the system assigns a new unique ID. Additional identifiers are recorded in the metadata.
Catalogue metadata
Another optional external identifier in the ie.xml is the catalogue identifier from the Gemeinsamer Verbundkatalog (Union Catalogue, GVK). By means of the SRU interface to the catalogue system, configured in Rosetta, the catalogue identifier is used to enrich the object with descriptive metadata.
The catalogue metadata of each individual object are deposited in a dedicated XML file, which is linked to the IE via metadata identifiers (mId)
Identifiers are allocated PREMIS-compliant for objects, agents, events and rights. The following table lists several examples of identifiers.
Examples of identifiers based on the PREMIS model

|---|---|
SIP ID | 539308 |
IE ID | IE2980431 |
REP ID | REP2980432 |

Producer ID | 40030044 |
Producer agent ID | 2122740 |
Plug-in ID | 58638365 |

Process ID | 50532321 |
Rights | |
Boilerplate ID | TIB_OA_mit_CC |
Access right policy ID | 16728 |
Retention policy ID | NO_RETENTION |
External identifiers
External identifiers can be recorded in Dublin Core format, such as a DOI, a handle or a URN.
Allocation of identifiers
Internal-system identifiers are automatically allocated by the system as unique identifiers. The identifiers are given different additions, depending on the object type.
Structural metadata
Structural metadata are stored in the ie.xml as DNX and METS elements.
TIB stores 1-n representations per IE, each consisting of 1-n files. Representations are described using the DNX element “Preservation type”. Each ie.xml contains the IDs of all associated representations and files. In the file group, files are assigned to a file ID via their path, and each file ID is also assigned to a representation ID. In the StructMap, the files per representation are arranged in a logical sequence that can be transferred to a viewer.
Structural metadata − assignment to METS and DNX elements
Metadatum | Element and metadata standard | Value |
|---|---|---|
Representations | ||
Original files | Preservation type (DNX) | MASTER |
Modified copy of original files before ingest | Preservation type (DNX) | PRE-INGEST_MODIFIED_MASTER |
Modified copy of original files after ingest | Preservation type (DNX) | MODIFIED_MASTER |
Access copy | Preservation type (DNX) | DERIVATIVE_COPY |
Relationships | ||
Belonging of files to a representation | fileGrp (METS) | REP ID, File ID, storage path to the file |
Coherence of files within a representation | structMap (METS) | Representation ID, label structure, file ID |
Restoration of authentic data structure | ||
Original file name | fileOriginalName (DNX) | Original file name |
Original file path | fileOriginalPath (DNX) | Original file path |
The relationships between files within a representation are recorded in the “structMap” METS element. In addition, the original file name and path of every file are recorded in the metadata, documenting which directory structure a file was stored in during deposit.
Technical metadata
Technical metadata are captured in Rosetta as DNX metadata. DNX was specified by the software manufacturer Ex Libris and is based on PREMIS, but extends the standard by further elements. DNX documentation is publicly available. Updating of DNX is managed and monitored by the Rosetta user community.
The PREMIS standard defines a number of “basic concepts” as technical metadata in the semantic units ObjectCharacteristics, SignificantProperties, OriginalName and Storage. The relevant concepts of the unit are provided in the table below. In this case, the PREMIS concept is mapped to the DNX element, as well as information about at which point the concept can be allocated values and whether TIB has implemented the recording.

Logging of preservation actions
Defined events
Modifications to AIPs are recorded at the IE level as DNX metadata. The DNX schema was specified by the software manufacturer Ex Libris and is based on PREMIS, but extends the standard by additional elements. DNX documentation is publicly available. Updating of DNX is managed and monitored by the Rosetta user community.
Several examples of defined events are described in the table below. The complete list of defined events is documented in the Rosetta Configuration Guide.
Examples of events

339 | Preservation plan has been created |
372 | Manually Set Format Library ID on File |
380 | Representation has been added |
381 | Risk identification performed on file |
397 | METS Validation Failed |
A user with the role of “Administrator” can define which events from the list should be logged.
Logging of event metadata
The system automatically records the defined event metadata. Event metadata are written to the ie.xml for every defined event.
Administrative metadata
Defined administrative metadata
Administrative metadata are captured as DNX metadata at different levels in Rosetta. DNX was specified by the software manufacturer Ex Libris and is based on PREMIS, but extends the standard by further elements. DNX documentation is publicly available.
At the IE level, the standardised name of the applicable licence agreement is recorded as the Dublin Core element dctersm:license. The applicable licence text is deposited in Rosetta as a “boilerplate”; the text contains information about which actions may be performed on the object.
TIB understands administrative metadata to mean:
- Metadata that document the provenance of objects
- Legal metadata
- Metadata recorded for the purpose of organising objects
