AW: [rda-datafabric-ig] dfig-terms

Hello,
Dublin Core Metadata Initiative has definitions for spatial and temporal coverage:
http://purl.org/dc/terms/spatial
http://purl.org/dc/terms/temporal
Unfortunately these definitions (“Spatial characteristics of the resource”, “Temporal characteristics of the resource”) are generic and may not be sufficient for communities which need to be more precise. But in order to improve semantic interoperability with Dublin Core, these definitions could be mentioned, and then extended as required by those who need to go down that road.
There are currently terms “metadata” and “descriptive metadata” in Peter’s list. You may consider adding the following metadata related terms, which are widely used in library community and elsewhere (definitions are from ISO/DIS 5127):
administrative metadata (metadata about the maintenance and housekeeping for records); divided into
- technical metadata (metadata covering the technical requirements and preconditions for processing a records),
- preservation metadata, and
- rights metadata
structural metadata (type of metadata that indicates how compound objects are put together)
ISO 5127 defines metadata as “data about other data, documents, or records that describes their content, context, structure, format, provenance, and/or rights”, and descriptive metadata as “type of metadata that describes a resource for purposes such as discovery and identification such as creator), title, and subject

Hallo Zhu,
is there a definition of the last two terms: spatial and temporal extent.
I think that at least in your community there must be some definitions around.
Correct?

Hi Peter,
Actually, I am unclear the scale of DFIG terms and what are the basic principles of selecting terms. So I try to add some terms I think they are very important to define, describe and use data. Hope it will useful to perfect DFIG terms.

Dear all,
i just grabbed all terms I could in DFIG documents and comments so far. I am sure that much is missing.
But it may give a first impression. Most of the terms are not well-defined and people are using different definitions.
Please, feel free to add terms and references.

Juha,
Thanks very much for your follow up to the latest discussion of RDA DFT
terms per Peter's list of terms from Data Fabric.

We do have a definition of
​
Administrative metadata in our term tool:
​​
Administrative metadata is a type of Metadata the provides information to
help manage a resource, such as when and how data was created, file type
and other technical information, and who can access it.
Administrative metadata is related to the interaction or use of metadata
within a specific system.
See http://smw-rda.esc.rzg.mpg.de/index.php/Administrative_metadata
This doesn't include al of your distinction of 3 parts to it, which seems
useful.
We do note:
"There are several subsets of administrative data. Representation described
in a Representation Object is one. Two others that are sometimes listed as
separate metadata types are:
Rights management metadata, which deals with intellectual property rights,
and
− Preservation metadata, "
Note we also have a Provenance Metadata concept with relates to if is not
identical to the preservation MD idea.
"Provenance information metadata concerning the creation, attribution, or
version history of managed data." See
http://smw-rda.esc.rzg.mpg.de/index.php/Provenance_metadata
We also have
Structural metadata in the tool.
A type of metadata that indicates how compound objects are put together.
See http://smw-rda.esc.rzg.mpg.de/index.php/Structural_metadata
Since thes are metadata definitions I defer to the various RDA metadata
groups to weigh in on this to see if they are comfortable adding things
like technical MD and rights MD. I've included Rebecca and Keith on this
email as a heads up and as an opportunity to comment.
Juha, will you be at P7 to continue this discussion and do you want time as
part of the DFT IG session??

Juha –
As you identify correctly, DC is not great for spatial coordinates (nor temporal for that matter).
For spatial coordinate systems metadata ISO191115 / EC INSPIRE standard is very good and widely used.
Juha: Yes, for geographical information metadata as specified in ISO 19115:2014 is not only a good solution, but also a mandatory one at least within EU. There is probably no other kind of metadata which is co-ordinated so strictly internationally.
I am not aware of similar overarching standard for temporal data. ISO 8601 concentrates just on how to express date, time or periods (which is of course useful too). A new version of the standard is under development, and it will support new functionalities, at least some of which may be of interest to this community.
You are right to mention administrative, technical etc. but in fact in many cases the same metadata elements may e used for multiple purposes so the classification you mention is more about usage than basic properties. Just as one example elements of rights data (copyright/database right) overlap heavily with preservation/curation since both are required for availability and access processing.
Juha: The way the national library of Finland has solved this in the practical level is that the METS containers we send to the digital archive will contain two kinds of rights metadata: copyright / license information embedded in MARC 21 descriptive metadata, and preservation related rights information expressed in PREMIS Rights. We use terms preservation related rights metadata (which apply only within the digital archive) and usage related rights metadata (which apply anywhere else).
The work ongoingin the various metadata groups of RDA is tending towards a common set of elements that can be used for multiple purposes (discovery, contextualisation (including provenance/quality/relevance), access (including rights)….
Juha: There is definitely plenty of overlap between metadata categories. For instance, libraries’ MARC 21 format for descriptive metadata contains a lot of administrative metadata elements and structural metadata links. IMO such overlap is OK, what is important is that we have a complete list of elements needed (which is what RDA metadata groups are doing).
Moreover, when managing electronic resources all these point of views can / should be taken into account, and that the necessary metadata elements can be used by those programs that need it. So, if the library system needs to know the copyright and licensing status of a research data set, that information should be available in MARC 21, while e.g. organizational repository using DSpace may prefer to have that metadata in Dublin Core.
All the best,
Juha
The proposed set (discussed at RDA P6 and at the Coordination meeting in Gaithersburg in December) set may be found on the MIG webpage (Metadata P6 Paris).

Juha: Yes, for geographical information metadata as specified in ISO 19115:2014 is not only a good solution, but also a mandatory one at least within EU. There is probably no other kind of metadata which is co-ordinated so strictly internationally.
I am not aware of similar overarching standard for temporal data. ISO 8601 concentrates just on how to express date, time or periods (which is of course useful too). A new version of the standard is under development, and it will support new functionalities, at least some of which may be of interest to this community.
You are right to mention administrative, technical etc. but in fact in many cases the same metadata elements may e used for multiple purposes so the classification you mention is more about usage than basic properties. Just as one example elements of rights data (copyright/database right) overlap heavily with preservation/curation since both are required for availability and access processing.
Juha: The way the national library of Finland has solved this in the practical level is that the METS containers we send to the digital archive will contain two kinds of rights metadata: copyright / license information embedded in MARC 21 descriptive metadata, and preservation related rights information expressed in PREMIS Rights. We use terms preservation related rights metadata (which apply only within the digital archive) and usage related rights metadata (which apply anywhere else).
The work ongoingin the various metadata groups of RDA is tending towards a common set of elements that can be used for multiple purposes (discovery, contextualisation (including provenance/quality/relevance), access (including rights)….
Juha: There is definitely plenty of overlap between metadata categories. For instance, libraries’ MARC 21 format for descriptive metadata contains a lot of administrative metadata elements and structural metadata links. IMO such overlap is OK, what is important is that we have a complete list of elements needed (which is what RDA metadata groups are doing).
Moreover, when managing electronic resources all these point of views can / should be taken into account, and that the necessary metadata elements can be used by those programs that need it. So, if the library system needs to know the copyright and licensing status of a research data set, that information should be available in MARC 21, while e.g. organizational repository using DSpace may prefer to have that metadata in Dublin Core.
All the best,
Juha

- preservation metadata, and

I think we agree! I have been concerned particularly with metadata interconverdion. Using CERIF as the canonical superset. RDA work to date seems to require this approach.

Hallo Zhu,
is there a definition of the last two terms: spatial and temporal extent.
I think that at least in your community there must be some definitions around.
Correct?

Hi Peter,
Actually, I am unclear the scale of DFIG terms and what are the basic principles of selecting terms. So I try to add some terms I think they are very important to define, describe and use data. Hope it will useful to perfect DFIG terms.
Best regards,

Dear all,
i just grabbed all terms I could in DFIG documents and comments so far. I am sure that much is missing.
But it may give a first impression. Most of the terms are not well-defined and people are using different definitions.
Please, feel free to add terms and references.

Just -
I think we agree! I have been concerned particularly with metadata interconverdion. Using CERIF as the canonical superset. RDA work to date seems to require this approach. Syntax conversion is difficult enough (graphs to hierarchies for example) but multilingual semantics conversion is a real challenge!

Juha –
As you identify correctly, DC is not great for spatial coordinates (nor temporal for that matter).
For spatial coordinate systems metadata ISO191115 / EC INSPIRE standard is very good and widely used.
Juha: Yes, for geographical information metadata as specified in ISO 19115:2014 is not only a good solution, but also a mandatory one at least within EU. There is probably no other kind of metadata which is co-ordinated so strictly internationally.
I am not aware of similar overarching standard for temporal data. ISO 8601 concentrates just on how to express date, time or periods (which is of course useful too). A new version of the standard is under development, and it will support new functionalities, at least some of which may be of interest to this community.
You are right to mention administrative, technical etc. but in fact in many cases the same metadata elements may e used for multiple purposes so the classification you mention is more about usage than basic properties. Just as one example elements of rights data (copyright/database right) overlap heavily with preservation/curation since both are required for availability and access processing.
Juha: The way the national library of Finland has solved this in the practical level is that the METS containers we send to the digital archive will contain two kinds of rights metadata: copyright / license information embedded in MARC 21 descriptive metadata, and preservation related rights information expressed in PREMIS Rights. We use terms preservation related rights metadata (which apply only within the digital archive) and usage related rights metadata (which apply anywhere else).
The work ongoingin the various metadata groups of RDA is tending towards a common set of elements that can be used for multiple purposes (discovery, contextualisation (including provenance/quality/relevance), access (including rights)….
Juha: There is definitely plenty of overlap between metadata categories. For instance, libraries’ MARC 21 format for descriptive metadata contains a lot of administrative metadata elements and structural metadata links. IMO such overlap is OK, what is important is that we have a complete list of elements needed (which is what RDA metadata groups are doing).
Moreover, when managing electronic resources all these point of views can / should be taken into account, and that the necessary metadata elements can be used by those programs that need it. So, if the library system needs to know the copyright and licensing status of a research data set, that information should be available in MARC 21, while e.g. organizational repository using DSpace may prefer to have that metadata in Dublin Core.
All the best,
Juha
The proposed set (discussed at RDA P6 and at the Coordination meeting in Gaithersburg in December) set may be found on the MIG webpage (Metadata P6 Paris).
With best wishes
Keith

Hello,
Dublin Core Metadata Initiative has definitions for spatial and temporal coverage:
http://purl.org/dc/terms/spatial
http://purl.org/dc/terms/temporal
Unfortunately these definitions (“Spatial characteristics of the resource”, “Temporal characteristics of the resource”) are generic and may not be sufficient for communities which need to be more precise. But in order to improve semantic interoperability with Dublin Core, these definitions could be mentioned, and then extended as required by those who need to go down that road.
There are currently terms “metadata” and “descriptive metadata” in Peter’s list. You may consider adding the following metadata related terms, which are widely used in library community and elsewhere (definitions are from ISO/DIS 5127):
administrative metadata (metadata about the maintenance and housekeeping for records); divided into
- technical metadata (metadata covering the technical requirements and preconditions for processing a records),
- preservation metadata, and
- rights metadata
structural metadata (type of metadata that indicates how compound objects are put together)
ISO 5127 defines metadata as “data about other data, documents, or records that describes their content, context, structure, format, provenance, and/or rights”, and descriptive metadata as “type of metadata that describes a resource for purposes such as discovery and identification such as creator), title, and subject
