portsjonid

Portsjonid is an identifier used in some nutrition and recipe data systems to label a discrete portion of a recipe or meal. It enables precise linking of ingredients and nutrient data to a specific serving and supports portion scaling and reporting. The term is not part of a widely adopted formal standard and is encountered mainly in vendor-specific schemas or localized datasets.

Origin and scope

The word portsjonid appears to derive from the concept of a portion, with the suffix id indicating an identifier. Its exact meaning and structure can vary by platform: in some systems it functions as a surrogate key, while in others it acts as a stable natural key that references a particular serving within a recipe.

Data model and relationships

In typical implementations, portsjonid is represented as a string or GUID. Related data often include recipe_id, portion_name, serving_size, unit, and nutritional fields such as calories and macronutrients. A single recipe may have multiple portsjonids to represent different serving sizes or portions, establishing a one-to-many relationship between recipes and portions.

Usage and practical considerations

Portsjonid supports consistent reference across components of a nutrition or meal-planning application, enabling accurate ingredient scaling and nutrient calculations per serving. Because there is no universal standard, porting data between systems may require mapping portsjonids to ensure semantic alignment and to maintain data integrity.

Interoperability and caveats

Due to the absence of a formal standard, portsjonid schemes differ across apps and databases. When exchanging data, developers should document the semantics of each portsjonid, enforce uniqueness, and provide mappings to any equivalent identifiers used by other systems.
