Overview
The Agriculture and Livestock Metadata Elements Set (Almes Core) is a structured metadata schema designed to enhance the FAIRness (Findability, Accessibility, Interoperability, and Reusability) of agricultural price index datasets. Developed and maintained by the Almes Core Management Group, the schema provides a standardized vocabulary for describing datasets related to agriculture, commodities, and price indexes.
The name “Almes Core” was chosen to reflect the schema’s broad and extensible design, allowing for future expansion into other agricultural domains beyond price index data.

Conceptual Model
This conceptual model represents the metadata schema for managing and documenting resources, datasets, and observations, primarily within the domain of agriculture and economic statistical operations. The model defines a set of classes and properties to describe how data is structured, with a particular focus on datasets and observations of product prices.
Classes
The model consists of three main classes:
- Resource
- Dataset
- Observation
Relationships Between Classes
- Resource is a general class that describes any entity that is published or curated by a single agent, such as a dataset, report, or other informational resources.
- Dataset is a subclass of Resource, representing structured data collections. A Dataset contains one or more Observations, which capture recorded data about specific agricultural products, including price, date, and currency.
- The relationship between Dataset and Observation is expressed through the
alm:hasObservation property, indicating that a dataset can have multiple observations associated with it.
Class Descriptions
1. Resource
Definition: A general class representing any resource published or curated by a single agent.
- URI:
https://www.w3.org/ns/dcat#Resource
- Properties:
dct:identifier (xsd:anyURI): An unambiguous reference to the resource within a given context.dc:title (rdfs:Literal): The title or name of the resource.dct:description (rdfs:Literal): A description of the resource, which may include an abstract, table of contents, or free-text account.dc:publisher (rdfs:Literal): The entity responsible for publishing the resource (e.g., person, organization, or service).dc:creator (rdfs:Literal): The entity primarily responsible for creating the resource.dct:modified (xsd:date): The date the resource was last modified.dct:hasVersion (rdfs:Literal): Version information about the resource.dct:language (rdfs:Literal): The language of the resource, represented as a controlled vocabulary (ISO 639).dct:license (xsd:anyURI): A legal document granting permission to use the resource.dc:rights (rdfs:Literal): Information about rights held over the resource.
2. Dataset
Definition: A structured collection of data, often used in economic and agricultural contexts to represent measurements and observations about products, prices, and other factors.
- URI:
https://www.w3.org/ns/dcat#Dataset
- Inherits from:
dcat:Resource
- Properties:
alm:productgroup (rdfs:Literal): A group of products resulting from agriculture or livestock, aggregated based on biological traits.alm:producttype (rdfs:Literal): The type of agricultural or livestock product represented in the dataset (e.g., soy, corn, cattle).alm:theme (rdfs:Literal): The main subject or topic of the dataset (e.g., price index, agricultural production).dcat:accessURL (xsd:anyURI): A URL providing access to the dataset (e.g., a landing page or SPARQL endpoint).dct:accrualPeriodicity (rdfs:Literal): The frequency at which items are added to the dataset.sdo:referenceQuantity (rdfs:Literal): The reference quantity for which a certain price applies (e.g., 1 EUR per 4 kWh of electricity).sdo:location (rdfs:Literal): The geographical location associated with the dataset.alm:statisticalMethod (xsd:anyURI): Summary of the statistical methods used to process the dataset.alm:descriptiveStatistics (rdfs:Literal): Descriptive statistics summarizing the dataset, such as mean, variance, and trends.sdo:startDate (xsd:date): The start date of the dataset (typically for time series data).sdo:endDate (xsd:date): The end date of the dataset. If the dataset is still active, this field remains empty.alm:hasObservation: A key property linking a dataset to multiple Observation entities that capture detailed information such as price, date, and currency for agricultural products.
3. Observation
Definition: An observation is a specific recorded data point, typically used to represent the price of an agricultural product at a specific point in time, along with other relevant attributes.
- URI:
https://w3id.org/AlmesCore#data
- Properties:
dc:date (xsd:date): The date or time period when the observation was made.sdo:price (xsd:float): The price of the product, represented as a floating-point number.sdo:currency (xsd:string): The currency in which the price is expressed, typically following ISO 4217 standards (e.g., “USD” for US dollars).
Key Relationships
alm:hasObservation
- Definition: A property that associates a Dataset with one or more Observation instances.
- Domain:
Dataset
- Range:
Observation
- Cardinality: A dataset may have zero or more observations. Each observation contains specific details such as price, date, and currency.
Example of Relationship:
- A Dataset could be a time series of agricultural product prices.
- Each Observation in the dataset would represent the price of a specific product (e.g., soy) on a particular date, expressed in a given currency (e.g., BRL for Brazilian Real).
Use Case Example
Consider an economic statistical operation that tracks the price of various agricultural products over time. In this scenario:
- Resource: Represents the overall collection of datasets published by an organization responsible for managing agricultural statistics.
- Dataset: Could represent the time series data for the price of different products, such as grains or livestock, categorized by product type and theme (e.g., Price Index for Domestic Agriculture).
- Observation: Individual data points within the dataset, capturing the price of a product at a given time and in a specific currency.

Date may be used to express temporal information at any level of granularity. Recommended practice is to express the date, date/time, or period of time according to ISO 8601-1 [ISO 8601-1] or a published profile of the ISO standard, such as the W3C Note on Date and Time Formats [W3CDTF] or the Extended Date/Time Format Specification [EDTF]. If the full date is unknown, month and year (YYYY-MM) or just year (YYYY) may be used. Date ranges may be specified using ISO 8601 period of time specification in which start and end dates are separated by a ‘/’ (slash) character. Either the start or end date may be missing. |
| Comment 2 |
In case the date is a range, sdo:startDate and sdo:ednDate should be used instead to indicate the beginning and the end of the period. |

Extended Almes Core
Extended Almes Core was created to support the use of the metadata schema in RDF, within the namespace https://w3id.org/AlmesCore/rdf#.
The publisher and creator properties describe the entities responsible for publishing the Datasets. To provide more detailed information about these entities beyond just their names, these properties can be instantiated using the Agent class, which includes attributes such as name, homepage, and email. Using the Agent class is optional in the Simple Almes Core, and mandatory in the Extended Almes Core.
The productGroup and productType properties may have subproperties productGroupURI, productGroupName, and productTypeURI, productTypeName, respectively. The use of this subproperties is not mandatory, but highly recommended.
As mentioned before, in the Simple Almes Core, location may provide only the name of the location in textual form. In Extended Almes Core, location should be instantiated using the GeoNamesFeature class, which has two properties: geoNamesName, to give the location name as it appears on the GeoNames ontology, and geoNamesID, to provide the URI of the concept representing a location within the GeoNames ontology.

| Comment 1 |
Date may be used to express temporal information at any level of granularity. Recommended practice is to express the date, date/time, or period of time according to ISO 8601-1 [ISO 8601-1] or a published profile of the ISO standard, such as the W3C Note on Date and Time Formats [W3CDTF] or the Extended Date/Time Format Specification [EDTF]. If the full date is unknown, month and year (YYYY-MM) or just year (YYYY) may be used. Date ranges may be specified using ISO 8601 period of time specification in which start and end dates are separated by a ‘/’ (slash) character. Either the start or end date may be missing. |
| Comment 2 |
In case the date is a range, sdo:startDate and sdo:ednDate should be used instead to indicate the beginning and the end of the period. |
