Indicate journal frequency with dct:accrualPriodicity & controlled values #59

In the DINI KIM context it was proposed to use |
The source field probably is 406. From the MAB documentation:

http://marc21rdf.info/ is up again. Here is the controlled value list for frequency of continuing resources in turtle:

No, it's not. In the ZDB it is Pica+ field
ZDB also implements the RDF approach we would like to implement, e.g. I can not find the controlled values in hbz Aleph export data, though, see for example http://lobid.org/hbz01/HT001387709. (I can neither find the information in the DNB MARC XML, see e.g. http://d-nb.info/011172355/about/marcxml where it should be in fields 853-855, subfield w.) If I am right and the information is not part of the hbz data, we won't be able to implement this. |
I found it in 052, 8-10. From the MAB documentation:
Regarding the matichng, the abbreviations are the same except for Mab d -> http://marc21rdf.info/terms/continuingfre#d |
We could also use bf:frequency as property. |
I second the use of bibframe frequency. We aren't limited to a specific set of controlled values with that. |
Not sure about the
? Here the complete entries:

+1 without the Erscheinungsfrequenz wrongly spelled (missing s). For non-libriarians the term is more explicit than Erscheinungsweise. |
- update labels providing German labels See #59.
Problem solved on data side, see http://test.lobid.org/resources/search?q=publication.frequency.label:terms&format=json or example resource (test) / example resource (production). I suppose that it is not shown in the frontend because the webpage is still cached (the labels.json has the URL in it). Right @fsteeg or @dr0i ? |
The problem I noted in #59 (comment) and via chat is still existent. Take for example HT015427971 (source, test). 052 looks like this: <controlfield tag="052">p||||||tz||||||</controlfield> In position 0, we have a Systematically, a lot of entries are wrong as position 7 is taken where you find the values that could all be in position 8. From the MAB documentation:
That is why we have so much http://marc21rdf.info/terms/continuingfre#i in the data as As a consequence, we have to add a period at each
|
Resolves last part of #59 (#59 (comment))
The last commit should fix it: Example (production) / example (test). |
An issue was opened for the wrongly shown frequency ids (#362). |
This is still not correct. The example file now has the wrong frequency = http://marc21rdf.info/terms/continuingfre#i ("dreimal wöchentlich"), although the MAB source has a <controlfield tag="052">z||||||td||||||</controlfield> @ChristophEwertowski, I suggest you just do what I already said twice (via chat and in #59 (comment)):
|
I just pushed a fix to the branch. Please review. |

I just learned that there are controlled values in ZDB data for frequency information. I will investigate this so that we can also add this to the RDF.
