Locating missing metadata for radio programmes by using the programme schedules
Programmes that are part of a series often have the name of the series as their title. In this case, a search for the series title results in a list of programmes with the same title. Depending on the number of programmes in the series, this list can be very long, and it can be a challenge to distinguish between the different programmes in the results list. This is even more true in the cases where the information about date and time is not correct or missing. In that case adding metadata to the materials might help you keep track of the different materials. It also enriches the material thereby making it easier for other users to find and work with the material. One way of finding additional metadata is to use the programme schedules. The programme schedules are a very useful source of metadata, including information about when and where a programme was broadcasted and possibly also the subject of the programme, who participated in the programme and the like. It also means that it is possible to find metadata – and thus information – about a programme even if the programme itself is not in LARM.fm.
The following example will describe the steps taken to enrich a programme from the series “Søndagsuniversitetet” (The Sunday University) from 1959. All names and descriptions are in Danish as they appear in the archive. The method described here might not be applicable in all cases because it depends on the availability of the programme schedule. All programme schedules should be available from 1925 up to and including 1983 but there might be individual schedules that are not available in the LARM.fm archive.
1) Search for Søndagsuniversitetet without using any of the filters. This will return 60 results, of which 28 are radio programmes and 32 are programme schedules. Narrow the result to only radio programmes by clicking the filter Radioprogrammer under Type. As you can see 13 of the radio programmes are called SØNDAGSUNIVERSITETET followed by just a season (sæson) number, while 15 of them have an additional title, for instance SØNDAGSUNIVERSITETET. 1. SÆSON: Udenrigshandel og produktion. The ones that have an additional title are materials where metadata has been added by a user in order to enrich the materials and to be able to tell the different programmes apart.
2) Choose the radio programme SØNDAGSUNIVERSITETET. 1. SÆSON: Udenrigshandel og produktion by clicking on it in the list of results. In the userinterface (if you are logged in) you will now see a timeline where you can listen to the radio programme and below you see the Radio archive metadata. You can see it says “Ca. udsendelsesdato: 1958.” under Resume, but there is no start og end time (it is stated as unknown).
3) Next to the Radio Archive metadata is another tab called Radio LARM metadata. Open this tab. This is the tab where users can add metadata to the material and also edit the existing LARM metadata (not the Archive metadata, these are fixed). You have to log in to LARM.fm to be able to edit metadata (log in is in the upper right corner). When you are logged in a pencil symbol is show in the rows where you can add/edit metadata. As you can see information has already been added, including date and time of the broadcast. This means that this programme will now show up if you search for this particular date – or the name of the lecturer or anything else added in LARM metadata.
4) Listen to the radio programme. At the very beginning the title, subject and host of the programme is introduced. This can then be added to the metadata. It is then possible to search for one or more of the words mentioned in the introduction. By using the words from the radio programme as search words it is possible to locate the programme schedule mentioning the broadcast of the programme. It is worth mentioning that not all programmes have such a thorough introduction, so in some cases it will require more listening to try to figure out what programme it is and what to search for in the programme schedules. But in this case, try for instance to search for udenrigshandel AND ølgaard (part of the subtitle of the individual programme and the name of the host) – AND is a boolean operation, cf. the LARM.fm manual. This search results in two programme schedules that can be studied in order to find information about the programme. You can watch a pdf with a digital version of the original document and because the document has been scanned and processed with optical character recognition software (OCR), the data from the programme schedule are also available below the pdf in the form of archive metadata which are searchable. Both files have metadata about the series of programmes and the programme schedule from 01/03/1959 mentions the specific programme Danmarks økonomi og udlandet. Udenrigshandel og produktion.
5) Now that the programme has been located in the programme schedule the date and time of the broadcast can be added to the LARM metadata. It is, of course, also possible to add additional relevant metadata to the material. Another option is to add annotations to the material. See more in the LARM.fm user manual.
