[design] clarify jrc needs

[pvgenuchten]

For me these 2 lines are not clear, what is expected here:

metadata-validator/docs/design.md

Lines 52 to 53 in 491ef48

	- adopt the ISO 19157 data quality measures
	- JRC does not want to discourage data providers from publishing metadata by visualizing, that they are not conformant with a set of rules

Line 52 - adopt the ISO 19157 data quality measures

• ISO 19157 (Geographic information — Data quality) is, technically, usually natively implemented in the validation tools. The measures from ISO 19157 describe, e.g. Completeness Commission/Omission (are all mandatory metadata elements present?, % of missing elements, etc.), or domain consistency (i.e. does the text string have the form/values/text as expected?).
• ISO 19115 is adopting the Data Quality classes from ISO 19157. This fact alone fulfils the requirement.
• In other words, the validation results can be later reported in line with the 19157, but at this point, this requirement doesn't affect the validation process.

Line 53 - JRC does not want to discourage data providers from publishing metadata by visualizing, that they are not conformant with a set of rules

• This relates to the discussions that the Validation results (especially from the INSPIRE validation) should not be publicly visualised in the catalogue. At least not the non-conformant results...
