Resource Models
Resources Models (RM), or graphs, are the models of any kind of resources. Like molds, they are not perfect but allow copies to be shared. RMs are CIDOC-CRM-based, with nodes connected to other nodes through directed edges (entities and properties).
List
All current EAMENA RMs are hosted here on GitHub
Heritage Places
Fields
Heritage Places counts 98 fields, some of them are mandatory (see MDS). The table below offers a short description of them, colored according to their categories (see again the MDS chart color).

Heritage Places fields with fields colored by categories: Assessment Summary, Resource Summary, Geometries, Geography, Archaeological Assessment, Condition Assessment, Environment Assessment, Access
- Structured data: Consist of controlled vocabularies, with possible values detailed in the BU form or on EAMENA's GitHub.
- Free text: Includes both strings and numerical values.
- Dates: Follow the ISO 8601 format (YYYY-MM-DD) for precision and standardization.
- EDTF: Adheres to the ISO 8601-2:2019 format, which allows for both fuzzy dates (to express uncertainty) and very precise timestamps (including hours and minutes).
- Boolean: Values represent binary choices such as yes/no or presence/absence.
- Resource instances: Are unique identifiers of related instances derived from another resource model (such as Information Resources, Grid Squares, etc.).
- GeoJSON feature collections: Include geographical coordinates and geometry types, which may be numerous and varied.
Entity-Relationship Diagram
Entity-Relationship Diagram (ERD) is the graphical representation of Heritages fields (CIDOC-CRM entities) and their relationships (CIDOC-CRM properties) to each other, that is to say the Heritage Place resource model
ERD of the EAMENA Heritage Place Resource Model with fieldnames (nodes) colored according to the minimum data standard (MDS): Assessment Summary, Resource Summary, Geometries, Geography, Archaeological Assessment, Condition Assessment, Environment Assessment, Access
Minimum data standards
Minimum data standards (MDS) are the mandatory fields that need to be completed for each heritage places recorded in the database.

Grid Squares
Grid Squares are 0.25 degrees in both longitude and latitude, covering the entire geographical scope of the EAMENA project, which spans the Middle East and North Africa (MENA) region from Afghanistan to Mauritania.
EAMENA geographical scope (Grid Squares perimeter)
Fields
With the current GeoJSON specification (RFC 7946) to encode geographical data1, the unique EAMENA specific field is 'Grid ID', the reference and unique number of the Grid Square (ex: E61N30-32).
