The messages all concern "VIEWS" (Queries, Abfragen).
Unfortunately, Microsoft Access has an extensive Query-Language which goes very far beyond standard SQL, is proprietary and not well documented, and cannot always be handled by SIARD. We have compromised by displaying errors on the Err tab, when we cannot convert a VIEW, but nevertheless proceed to download the actual data tables.
You should be able to see the content of all tables, but all of the VIEWS mentioned in the error messages are missing.
If the Queries are to be archived, you will have to archive the code separately. We doubt, that the code can be preserved meaningfully for many decades. If you are mainly interested in archiving the tabular data, the resulting SIARD file should be fine.
I shall test with your database, whether I can see any other problems.
I have tested with your database. The download works correctly. The actual table data are archived. The queries. however, are not all archived. This corresponds to the goal of SIARD to garantee long-term preservation of DATA and not of CODE. (We do believe that the data will be preserved in a way that is meaningful in 50 years. The MS code, however, will most probably not be executable oder understandable then.
If you want to preserve the text of the queries separately (not as part of an SQL database), you can export them as text and archive them together with the SIARD file.
See e.g. https://stackoverflow.com/questions/1275502/export-all-ms-access-sql-queries-to-text-files
(By the way: I am working in an office which is located in the area of the former Webmaschinen-Fabrik Rüti ...)
I saw that about your office and found it quite funny. Sending the data back to its former location for further processing etc
I do agree that it seems properly archived in SIARD but a few error messages still confound me.
That is why I think something is still not quite right. It could have something to do with my installation of the SIARD GUI if you did not encounter any unusual behavior.
I had no problems opening the SIARD file using SIARD. I cannot really be responsible for KOST-Val. But it would certainly be interesting to know, why it fails. I also opened it using PKZIP without any problems.
I first tried to open the SIARD file using an old 7ZIP version (2010). I failed to open it. Full 64-bit support came relatively late for many ZIP applications. So I tried with a current version (2021). With that I could open the SIARD file without any problems.
I suspect that the KOST-Val validation fails, because JHOVE have not updated their version verification for SIARD. I tried to convince the people in the Swiss Federal Archives ti sort that out. Unfortunately I probably did not (yet) succeed.
To summarize: I believe, everything is quite right. The SIARD file from you MS Access database can be opened and examined using SIARD, PKZIP and 7ZIP. In all three cases the metadata.xml is complete and readable.
Using the latest version 2.1.134, Java Version 1.8.0_151, Windows 10 64 bit
I tried downloading a Microsoft Access DB that works when opened alone. There are errors when downloading it. Since the content is not confidential, I uploaded it here (please download it within the week before the link expires, the issue itself is not pressing, however).
Downloading it with the "archive views as tables" checkmark produces one error visible in the "Err" tab:
Downloading it without extra options produces the following errors in the "Err" tab, after which it says "erfolgreich heruntergeladen" but shows the error message quoted in the title:
