formátumleírója

A "formátumleírója" is a Hungarian term that translates to "format descriptor" or "format specifier" in English. It refers to a component or a piece of data that defines the structure, layout, and characteristics of another data set or file. In essence, a format descriptor dictates how information should be interpreted and organized.

This concept is widely used in computing and data management. For example, in file formats, a format descriptor might specify the order of fields, their data types (e.g., integer, string, date), their lengths, and any delimiters or separators used. This allows software applications to correctly read, parse, and process the data contained within a file.

Format descriptors are crucial for interoperability, ensuring that different systems or programs can understand and exchange data without loss of information. They can be embedded within the data itself, stored in a separate metadata file, or be part of a software’s internal logic. The complexity of a format descriptor can range from very simple, like defining a comma-separated value (CSV) file, to highly complex, as seen in structured document formats like XML or JSON, or binary file formats used in specialized applications. Without a clear format descriptor, data would be ambiguous and largely unusable.
