| Requirement Form Data Exchange Functionality | Description | This form expresses the general need of exchanging data and also offers an extension for specifying the data formats | |
| Comments | The first three extensions may be applied at most once. Fourth and fifth extensions may be applied more than once, and they require the third extension to be applied before (see restrictions on parameters). | ||

| Fixed Part | Question text | ---- | Form text | The system shall offer functionalities for importing and exporting data. |
| Extended Part Data Exchange Formats | Question text | ---- | Form text | The system shall be able to %exchangeDirection% data in %formNames% formats |
| Parameter | Metric | ||
| exchangeDirection: represents one of the possible directions for exchanging data | ExchangeDirection: ExchangeDirections= Domain(Import, Export, Import and Export | ||
| formNames: is a non-empty set of names of data formats, if the value is “Some Standard”, then the size must be one | FormatTypes: FormatTypes = Set(FormatType) FormatType = Domain(Some Standard, XML,HTML,...) | ||
| Extended Part Data Exchange Frequency | Question text | ---- | Form text | The system shall be able to exchange data with %extSystems% systems every %amountOfTime% %timeUnit% |
| Parameter | Metric | ||
| timeUnit: is a unit of time corresponding to the units of frequency for exchanging data | TimeUnitType: TimeUnitType = Domain(Days, Hours, Minutes, Seconds, Miliseconds, ...) | ||
| extSystems: is a non-empty set of software names (systems, database, etc.); it must be a subset of the same parameter in the first extension | SoftwareNames: SoftwareNames = Set(SoftwareName) SoftwareName = String | ||
| amountOfTime: is a number that indicates frequency | amountOfTimeUnitType : | ||
| Extended Part Data Exchange Triggers | Question text | ---- | Form text | The system shall be able to exchange data with %extSystems% systems when %condNames% happens |
| Parameter | Metric | ||
| condNames: is a non-empty set of conditions that trigger the data exchange | ConditionNames: ConditionNames = Set(ConditionName) ConditionName = String | ||
| extSystems: is a non-empty set of software names (systems, database, etc.); it must be a subset of the same parameter in the first extension | SoftwareNames: SoftwareNames = Set(SoftwareName) SoftwareName = String | ||
| Extended Part External System to Exchange Data with | Question text | ---- | Form text | The system shall be able to exchange data with the %extSystems% systems |
| Parameter | Metric | ||
| extSystems: is a non-empty set of software names (systems, database, etc.) | SoftwareNames: SoftwareNames = Set(SoftwareName) SoftwareName = String | ||
| Extended Part Metadata Formats | Question text | ---- | Form text | The system shall be able to exchange metadata of the system resources in %metFormat% format |
| Parameter | Metric | ||
| metFormat: is a non-empty set of metadata format, if the value is “Some Standard”, then the size must be one | MetadataFormats: MetadataFormats = Set(MetadataFormat) MetadataFormat = Domain(Some Standard, Non-Propietary, \nXML, EDI, OBF, …)\n | ||
