    Hi,

    Why do we have bi-directional relationship between serviceCategory and serviceCandidate?

    Same is not the case between
    • serviceCatalog and serviceCategory OR
    • serviceCandidate and serviceSpecification

    This will result in overhead in maintaining the relationship while making changes to either resource objects. Please clarify.

    Hi,
    The relationship cardinalities between serviceCatalog and serviceCategory or between serviceCandidate and serviceSpecification is 1-0..n or 0..m-1. But The relationship cardinality between serviceCategory and serviceCandidate is 0..n-0..m. This means a service candidate may fall into multiple categories while each category may include multiple service candidates. You may come with different flavors of implementing such n-m relationships to satisfy queries like what categories does a service candidate belong to? or what service candidates included in a given category? The API data model introduced bi-directional relationship to satisfy such query requirements.
    Thanks,
    Kamal

    These APIs are not working on my iOS. I am facing iTunes error 9. Please help me to fix it. I need some useful ideas.

    Hi Allen
    Can you supply additional information regarding "APIs not working". In general, the Open API project defines interfaces, not implementations. Some APIs do have a reference implementation, I am personally not familiar with how the reference implementation works - you could try reaching out to Henrique Rodrigues​ for more info on that.
