General information about the metadata of the Maya Image Archive and how to search the database
The Maya Image Archive contains collections of digitized images that are presented as the entity type “Medium” which is related to a variety of other entity types such as Person, Provenance, Place, Collection or Holder. Each entity type has several properties and several possible relations.

For a quick start, here is a video that shows the explorative search in our database using a short example:

Following the terminology of the database there is a difference between the abstract metadata schema elements and the actually implemented elements:
Entity Type (abstract) → Entity (implemented)
When an entity type is implemented it becomes an actual entity.

Relation (abstract)→ Relationship (implemented)
When a relation is implemented it becomes an actual relationship.

All implemented entities are represented with their various specific relationships in relation to one another via a graph-based structure.

This graph connects the following possible entity types by various types of relations (with given dataset fields) as illustrated below:

Entity Types


  • Medium
    The entity type Medium refers to a displayed digitized image of the archival record. Each image is stored in jpg-format and can be downloaded in its original size.
      Medium Properties
    • The field “Medium Name” refers to the name of the medium. It is taken from the name of the respective jpg-file uploaded into the Maya Image Archive. The
      naming-procedure is done automatically by the software.
    • The field “Comment” is used for any kind of additional information, entered manually by users of the Maya
      Image Archive. The field “Comment” is provided in every entity input form.
    • The field “Type” is a ConedaKOR default field that is used in the Maya Image Archive for
      the type of medium. Only visual media are stored in the database. A controlled vocabulary is provided here (e.g. photograph, drawing, manuscript, typescript,
      printout).
    • The field “Dating information” provides the date when the medium was created (e.g. a photograph was taken). It shows a field “Type of Dating” which is
      composed of the key “Year” and its associated value. The value for the respective year is a four-digit number.
    • The field “Picture Number” refers to the number of
      the digitized media file.
    • The field “Folder Number” refers to the number of the folder of the digitized media file.
    • The field “Image Description”
      provides a general description of the medium.

      automatic generation of the rights statement.
    • The field “Digitized by” provides information about the creator of the digitized Medium.
    • The field
      “Contributor by” provides information about the contributor who contributes further information (metadata) to the digitized Medium.

  • Provenance
    The entity type Provenance refers to the provenance of the artefact – e.g. it refers to the archaeological site (less specific location) where the depicted artefact was originally found.
    If the provenance is unknown, it is marked „PNK“ („provenance not known“). If the provenance of the depicted artefact is known, the name of the respective archaeological site or area is given. If a known archaeological site is also recorded in the project database, a link will be provided to that archaeological site’s record in the project database.
      Provenance Properties
    • The field “Provenance Name” refers to the provenance of the depicted artefact. It provides the name of the archaeological site where the depicted artefact originates from. If the place of origin of an artefact is not known or cannot be identified, it is marked as “PNK” (= “provenance not known”).
    • The field “Distinct Provenance Name” provides information to identify the given archaeological site unambiguously by using a distinct acronym.

      If the provenance of the artefact is unknown, it will be set as „PNK“ („Provenance not known“).
      If the artefact is also recorded in the project database, a link will be provided to that artefact’s record in the project database.

Types of Relations
The list of possible bidirectional relations between the entity types and a number of actually created relationships can be accessed here: List of Relations

Statistics
The page Statistics shows how many entities of each entity type and how many implemented relationships of each possible relation the database currently has.


Searchability
All entities can be searched by either a Simple Search or by an Expert Search
according to their built relationships or particular properties of the entities.


Navigating the System
The KOR system and user interface are designed in such a way that the user can move freely within the system. The relationships thus serve as paths by means of which one can arrive at other entities. Every entity page presents an overview of all relationships with other entities in the system. Clicking on an entity leads to its view page, where additional relationships are shown.
In addition to basic information, the relationships in image searches also offer an alternative to conducting a search query via the search menu. Thus, on the entity page of e.g. an artist, all works associated with this person can be shown, including the relevant images.


Specific Help Sections
Each one of the database functions provides the user with a help button (“?”).
The help text appears when “?” is clicked.
