Explanation of “Media Art Field”


The formulation of a metadata schema was carried out in the “Media Art Field”, which handles information about often impermanent and very one-off works of art, in order to express the search results of the database of post-war Japanese media-art history.
The group of the works of media art is positioned as the structural components of the “events” asked the society, and as of February 2016, records of media art works have been registered in numbers of approximately 10,000 cases of “Basic Information” and approximately 60,000 cases of “Detailed Information”.

In this database, information is registered on events at each and every venue, as well as information on all of the works which make up each event, and on all human factors and roles relating to not only the creators of media art, but also persons engaged in the events and works etc.
In addition to works already preserved and maintained in museums for their collections etc., information on works whose form has changed event by event, works whose whereabouts have been unknown, works which have already been lost and recreated are comprehensively registered as components of each event.

Search results are displayed in order of decades (chronologically).
The coordinates of a work’s genesis, contiguity, information on related literature, collections, and information on the ownership of archived materials can be checked as search results within the layers of organized and listed records. You can overview lists of keyword searches interspersed amongst multiple records of events, or display all detailed information on a single event. You can immediately change the information set that you wish to list by clicking on specific parts of the values displayed and carrying out further searches.

The event’s printed materials, related literature and archived materials which make up the source resources within the database are also appropriately registered, and can be used for bibliographic searches.
As there are many examples of media art works leaving indirect traces of themselves in photo records, audio records and film records, the existence of photographic records in newspaper and magazine articles etc. is also noted.

Nodes for Records Constituting Basic Information and Detailed Information on Events

Attribute values registered to A-level nodes (information paradigms) constitute events’ Basic Information.

A-level Nodes

Attribute values for B/C-level nodes branching off from the values of A-level device nodes (A6) constitute events’ Detailed Information.

A-level Terminal Nodes

Data is constituted so that event’s Detailed Information is linked to its Basic Information. For convenience, Basic Information is designated A-level, Detailed Information is designated B-level, and information relating to human factors is designated C-level.


About “Sub-events”

Sub-events” positioned as the attribute value of node B4 are allocated into the following five systems within events’ Detailed Information.

Detailed Information System 1 Event Components (Prior)
System 2 Event Components (Posterior)
System 3 Event-based Printed Matter *Source for Prior Information
System 4 Bibliographical Data *Source for Posterior Information
System 5 Archival Materials

Segmentation of Attribute Values in Nodes

Attribute values segmented in each node are as follows.

Relative Number Relative value of record in nodes
Classification Definition Standard value allocated to nodes are appropriately supplemented with (.)
Title Value taken from source (Japanese transcription/alphabetical transcription)
Typical Transcription Type-concept taken from source (Japanese transcription/alphabetical transcription)

*Information recorded in each source is registered with the transcription as- is.
Resources other than “Classification Definition” all correspond to a specific source. Writing which can be judged as being a typical expression is taken separately from the source apart from “Classification Definition” only where possible.

Layout/Sample (View)

The following chart is a layout sample extracted from part of the database’s search results.
For example, after information belonging to the specific “event series” is listed as in this chart, a further search can be performed by clicking values such as “venue”, “work”, “human factors” etc., and you can reorganize the order of the information.

●Attribute Value

Attribute Value Meaning
* (asterisk) No Attribute Value' there is no attribute value to be input into that cell in the future.
Empty Currently Work-In-Process (Not Entered) When temporarily leaving specific cells empty which attribute value can be entered during procedures (for work efficiency).
[et al.] Use when it is suggested that there are multiple unknown items in the source writing such as “including ○○○○○” etc., and the multiplication of those items (those lines) is possible.
[unknown] Unknown. Use when information taken from the source is insufficient, and attribute values cannot be entered into specific cells.
