Use Case: a gigapixel digitization of a two-dimensional artwork

The following use case describes how to package a gigapixel reproduction of a two-dimensional artwork such as a drawing or painting. The reproduction contains multiple flavours of photoregistration: with frame, without frame, stitched, or as partial captures. It includes:

  • TIFF files;
  • an Adobe Photoshop PSB file
  • basic descriptive metadata;
  • basic preservation metadata.

It uses the material-artwork SIP profile.

The content

The following content is provided for packaging:

cf9j41p15z_overzichtsopname_metlijst_tiff.tiff An image file in the TIFF file format containing a photoregistration of an ‘Uur- en kalenderwijzerplaat’ with the frame included.
cf9j41p15z_overzichtsopname_zonderlijst_tiff.tiff An image file in the TIFF file format containing a photoregistration of the ‘Uur- en kalenderwijzerplaat’ without the frame.
cf9j41p15z_stitch_bigtiff.tiff A stiched very high-resolution image file in the TIFF file format containing a photoregistration of the ‘Uur- en kalenderwijzerplaat’.
cf9j41p15z_stitch_psb.psb A stitched very high-resolution image file in the Adobe Photoshop Large Document Format containing a photoregistration of the ‘Uur- en kalenderwijzerplaat’.
cf9j41p15z_target_tiff.tiff A reference image file in the TIFF file format for calibrating the photoregistration hardware.
cf9j41p15z_Kolom1_deelopname1_tiff.tiff
cf9j41p15z_Kolom1_deelopname2_tiff.tiff
...
cf9j41p15z_Kolom5_deelopname6_tiff.tiff		 A very high-resolution image split into multiple files in the TIFF file format containing a photoregistration of the ‘Uur- en kalenderwijzerplaat’.
metadata.xml A metadata record describing the ‘Uur- en kalenderwijzerplaat’.

The metadata record can contain the following information:

  • the title of the work;
  • a description of the work;
  • a local identifier (e.g. Inventarisnummer)
  • the date the work was created;
  • the dimensions of the work;
  • the name, birthdate and deathdate of the artist;
  • a list of meemoo licenses;
  • some keywords;
  • the md5 checksums of the media files;
  • rights credits;
  • …

Some of the metadata above is supplied in both English and Dutch.

Applying the core concepts

Since the metadata only describes a single artwork, we can consider it as the single Intellectual Entity in the SIP.

We can distinguish a couple of file sets (in the TIFF or PSB file format) that represent the work in some manner: an overview with frame, an overview without frame, a stitched high-resolution image, a high-resolution image in parts, and a camera calibration target recording.

Since each set of files can have a meaning on its own (i.e. one could focus on one of the TIFF files to get an idea of what the painting looks like), they are split into separate representations. This results in the following application of the core concepts:

Intellectual Entity the ‘Uur- en kalenderwijzerplaat’
Representation 1 the access copy of the painting with frame
Representation 2 the access copy of the painting without frame
Representation 3 the first archive master: a high-resolution stitched representation in TIFF format
Representation 4 the second archive master: a high-resolution stitched representation in Adobe Photoshop Large Document Format
Representation 5 the second archive master: a high-resolution non-stitched representation
Representation 6 the calibration result
Files (rep. 1) the TIFF file: cf9j41p15z_overzichtsopname_metlijst_tiff.tiff
Files (rep. 2) the TIFF file: cf9j41p15z_overzichtsopname_zonderlijst_tiff.tiff
Files (rep. 3) the TIFF file: cf9j41p15z_stitch_bigtiff.tiff
Files (rep. 4) the PSB file: cf9j41p15z_stitch_psb.psb
Files (rep. 5) the TIFF files: cf9j41p15z_Kolom1_deelopname1_tiff.tiff, cf9j41p15z_Kolom1_deelopname2_tiff.tiff, …, cf9j41p15z_Kolom5_deelopname6_tiff.tiff
Files (rep. 6) the TIFF file: cf9j41p15z_target_tiff.tiff

This case relies on the material-artwork profile because:

  • there is one IE and multiple representations;
  • the artwork can be described using a combination of DCTERMS and a Schema.org;

Directory structure

We package the above in a meemoo SIP named 2D_fa307608-35c3-11ed-9243-7e92631d7d27.zip. It has the following directory structure:

The metadata

In total, the SIP contains 13 metadata files:

data/metadata/descriptive/dc+schema.xml Descriptive metadata about the IE residing at the package level using the DCTERMS and Schema metadata schema.
data/metadata/preservation/premis.xml Preservation metadata about the IE residing at the package level, including any PREMIS events related to the SIP/package/representations.
data/representations/representation_1/metadata/preservation/premis.xml Preservation metadata about the first representation and TIFF file residing at the representation level.
data/representations/representation_2/metadata/preservation/premis.xml Preservation metadata about the second representation and TIFF file residing at the representation level.
data/representations/representation_3/metadata/preservation/premis.xml Preservation metadata about the third representation and TIFF file residing at the representation level.
data/representations/representation_4/metadata/preservation/premis.xml Preservation metadata about the fourth representation and PSB file residing at the representation level.
data/representations/representation_5/metadata/preservation/premis.xml Preservation metadata about the fifth representation and TIFF files residing at the representation level.
data/representations/representation_6/metadata/preservation/premis.xml Preservation metadata about the sixth representation and TIFF file residing at the representation level.

/data/metadata/descriptive/dc+schema.xml

The dc+schema.xml of the package level describes the IE using the DCTERMS and the Schema metadata models. It contains minimal metadata such as a title, a description, an identifier, a date of creation and of issuance, and additional metadata such as the dimensions of the artwork, information about the artist, the art medium and the type of artwork.

The identifier in the <dcterms:identifier/> element is used to link the dc+schema.xml file to the corresponding PREMIS object in the preservation/premis.xml file of the package level (see here for more information).

data/metadata/preservation/premis.xml

The premis.xml of the package level describes the IE and the relationships with its representations. It also contains a digitization event that details how the TIFF files were created and by whom.

Note that the identifier in the <premis:objectIdentifier> element is shared with the <dcterms:identifier/> (in the descriptive/dc+schema.xml file) element in order to link the PREMIS IE object to its description.

data/representations/representation_4/metadata/preservation/premis.xml

The premis.xml file of the fourth representation describes two PREMIS objects:

  1. the representation;
  2. the PSB file cf9j41p15z_stitch_psb.psb;

It also describes the various relationships between these objects:

  1. the relation between the representation and the IE at the package level;
  2. the relations between the representation and the PSB file;

The premis.xml file of representation 1, 2, 3 have an identical structure.

data/representations/representation_5/metadata/preservation/premis.xml

The premis.xml file of the fifth representation describes 30 PREMIS objects (of which the first two are shown in the example below):

  1. the representation;
  2. the nine TIFF files cf9j41p15z_Kolom1_deelopname1_tiff.tiff, cf9j41p15z_Kolom1_deelopname2_tiff.tiff, …, cf9j41p15z_Kolom5_deelopname6_tiff.tiff;

It also describes the various relationships between these objects:

  1. the relation between the representation and the IE at the package level;
  2. the relations between the representation and the TIFF files;
