I'm developing an XSD scheme for SOAP-based web-service that provides financial calculations. Service response contains historical performance of portfolios of investments and different measures: rates of returns, standard deviations etc.
I'd like to know if there are some well known standards for such information? For example:
- how many decimal digits should values have;
- how currency/percentage/date/etc values are formatted in SOAP response;
- any standard enumerations for data types;
- any standard structures.
Do you follow any internal standards in your web-services? Can you suggest anything?
Thanks
