Sound and Vision Archive

This is the current audiovisual collection of The Netherlands Institute for Sound and Vision (NISV), one of the most important Dutch audiovisual archives, which collects, looks after, and provides access to over 70% of the Dutch audio-visual heritage. This version of the collection uses data from DAAN, the new media management system for NISV, which went into use in July 2018. The metadata model of DAAN is different to that of the previous media management system, so you will notice differences in the metadata compared to the old Audiovisual Collection. In principle, the same metadata is available, but the names of the fields and their structure have changed. See the bottom of this page for more information.

The import of this collection is not yet complete. It contains most of the items that were in the old Audiovisual Collection, and many new items from recent years. Not all items have had their media imported, the number of items with media will increase as the import progresses.

The following figures give answers to common questions about the composition of this collection:

What part of the collection is included in the Media Suite?

Via the Media Suite, The Netherlands Institute for Sound and Vision offers access to its entire audiovisual collection. The initial import of this collection into the Media Suite is still running, so not all items from the old Audiovisual Collection are available. The collection already contains many new items that were not available in the old collection, however, it does not yet contain every recent item.

What years does the archive cover?

The NISV audiovisual collection includes items from 1877 to the present day. items-over-time

Figure 1: Number of programs in the archive over time

As the import is not yet complete, not all items are present. This includes both recent items and items that were in the old Audiovisual Collection. The difference is visible in the graph below: comparison-items-over-time

How often is the data updated in the Media Suite?

This collection is currently being imported, so it is not yet complete. Once complete, it will be updated daily.

What kind of media is included?

What portion of the collection is digital?

Does the collection include enrichments?

Progressively, the NISV audiovisual collection is being enriched with automatic speech recognition (ASR) transcripts. The old Audiovisual Collection contains many ASR transcripts. These have not yet been transferred to the new collection, this will happen in due course. New ASR transcripts will be added to this collection over time.

More recent items in the NISV collection contain face recognition, speaker recognition and extracted thesaurus labels. These will be made available in the Media Suite in due course.

Differences between the metadata fields of DAAN and iMMix

The DAAN system for storing archive metadata about Sound and Vision archive items uses a different data model to the previous system, iMMix. The existing iMMix data has been migrated to the DAAN model, and the content of all important fields has been preserved. The way some information is modelled has changed, some administrative fields have been removed, and some important areas, such as IPR, have been extended to have more metadata fields.

Metadata fields with the same meaning in both iMMix and DAAN have been given the same labels in the Media Suite, so you should notice no difference for the bulk of the metadata. Where the structure of fields has changed, you will see a change in the names of the metadata fields. The biggest difference in existing fields is that ‘segment’ fields, those relating to clips within a program, now start with ‘logTrackItems.ltScenedesc’. DAAN also has many new fields with enrichment information, such as face recognition, extracted labels etc. These appear with the prefix ‘logTrackItems’ at present. In due course, as these are further integrated into the Media Suite, they will be given more user-friendly labels. The next section describes the main differences you will see when using the Media Suite

Differences when using the Media Suite

Resource Viewer

The viewer shows the same information for DAAN programs as for iMMix. The same labels have been used, so you should not notice a difference in the headings. The date format has changed, so you will now see dates in the format ‘year-month-day’ instead of ‘day-month- year’. E.g. an item from 10th November 1997 will have the date ‘1997-11-10’. When clicking on the ‘full metadata’ button, you will see the metadata from the DAAN model, so this will appear very differently. To understand this metadata, see the ‘Advanced information’ section below.

Finding specific resources

You may have links or bookmarks to resources from the old Sound and Vision (iMMix) collection. These will not work for the new Sound and Vision (DAAN) collection. To find a specific resource from iMMix in the DAAN collection, first look it up in the old Sound and Vision collection and note the ResourceId, which has the format ‘12345@program’. The DAAN resource has a very similar ID; to construct it take the numbers before the @ from the iMMix ID, and add ‘PGM’ in front of them. E.g. ‘PGM12345’. You can then select the DAAN collection and enter this ID as a search term to find your resource.

Search tool

The default search facets have the same labels as in iMMix. When selecting a date field or adding a new facet, you will notice more fields in the list. Most of the fields common to iMMix and DAAN have the same labels. The biggest difference in existing fields is that ‘segment’ fields, those relating to clips within a program, now start with ‘logTrackItems.ltScenedesc’. Use the Inspect tool to see descriptions of the fields.

When selecting a field for analysis, you will notice more fields in the list. Most of the fields common to iMMix and DAAN have the same labels. The biggest difference in existing fields is that ‘segment’ fields, those relating to clips within a program, now start with ‘logTrackItems.ltScenedesc’.

Advanced information about the differences in the data model

Both the iMMix and DAAN data models have information about a program and the series and season it was part of. Unlike iMMix, DAAN does not require a program to have a season and series, so these may be omitted. Both models also have information about when the program was broadcast (publication) and when it was recorded (recording/recordinginformation).

The key differences between the DAAN and iMMix models are summarised below:

  • Clips within a program, e.g. the weather forecast within a news program, were previously modelled as ‘segments’. These are now modelled as ‘scene descriptions’. At present, field names relating to scene descriptions all start with ‘logTrackItems.ltSceneDesc’.
  • Timing information has been moved from carriers (now called ‘asset items’) to technical logtrack items. These fields start with ‘logTrackItems.ltTechnical’.
  • Fields relating to rights have been changed a great deal. There are many fields related to IPR that start with ‘program.ipr’. Additional relevant fields are program.currentrightsholder, program.rightsdeterminationdate, program.rightslicense, program.rightslicensenote, program.rightslicenseterms
  • DAAN has many new fields with enrichment information, such as face recognition, extracted labels etc. These appear with the prefix ‘logTrackItems’ at present. In due course, as these are further integrated into the Media Suite, they will be given more user-friendly labels.

Look at the "Overview iMMix DAAN metadata.csv" spreadsheet to see exactly which iMMix metadata fields correspond to which DAAN metadata fields. Many of the DAAN metadata fields beginning with ‘program’ are also available at series or season level, simply replace ‘program’ with ‘series’ or ‘season’.
