Gagnasafn

A gagnasafn is a collection of data intended for analysis and interpretation. In its simplest form it is organized as a set of records (rows), each describing an observed entity or event, and a set of attributes (columns) that describe the properties of those observations. A gagnasafn can contain numeric, categorical, textual, or multimedia data and may originate from surveys, experiments, sensors, administrative systems, or compiled sources.

Datasets typically include metadata that explains what the data represent, how they were collected, and any limitations or biases. This metadata may cover the variables, data types, units of measurement, time stamps, geographic references, licensing, and provenance. Quality considerations such as missing values, errors, inconsistencies, and sampling bias are common concerns in a gagnasafn and influence how the data can be used.

Common formats for gagnasöfn include structured files like CSV, JSON, and XML, as well as database tables or specialized formats for large or complex data. Interoperability and accessibility are often enhanced by adhering to standards for metadata and data quality, and by clear licensing terms. Applications range from statistical analysis and research to machine learning, reporting, and public open-data initiatives. Privacy and ethical considerations, including anonymization and compliance with data protection laws, are important when handling sensitive information.
