Many documentation dialects include mechanisms for connecting people and organizations to metadata records. There are two general approaches to these connections. The first involves including the roles of the people in the names of the metadata element's. For example, the NetCDF Attribute Convention for Data Discovery includes fields titled creator_name, creator_email, and creator_url. This approach makes it difficult to standardize because new standard elements must be added in order to add a new role, i.e. processor_name, processor_email, processor_URL. The second approach centers around a generic description of a person or an organization that includes an attribute that gives the role they play with respect to the resource being documented. This approach allows additions by extending the list of roles. See NetCDF, HDF, and ISO Metadata for more details on this approach.
Connecting people to resources is an important role of metadata. In addition, it is critical to describe people's role with respect to the resource.
The DIF dialect differentiates clearly between documentation of people and organizations. People are documented using the Personnel object with roles of DIF AUTHOR, INVESTIGATOR, and TECHNICAL CONTACT:
<dif:Personnel> <dif:Role/> <dif:First_Name/> <dif:Middle_Name/> <dif:Last_Name/> <dif:Email/> <dif:Phone/> <dif:Fax/> <dif:Contact_Address> <dif:Address/> <dif:City/> <dif:Province_or_State/> <dif:Postal_Code/> <dif:Country/> </dif:Contact_Address> </dif:Personnel>
The dialect includes information for one type of organization: the Data Center that distributes the data. The Data Centers are documented using the DataCenter object:
<dif:Data_Center> <dif:Data_Center_Name> <dif:Short_Name/> <dif:Long_Name/> </dif:Data_Center_Name> <dif:Data_Center_URL/> <dif:Data_Set_ID/> <dif:Personnel> <dif:Role/> <dif:First_Name/> <dif:Middle_Name/> <dif:Last_Name/> <dif:Email/> <dif:Phone/> <dif:Fax/> <dif:Contact_Address> <dif:Address/> <dif:City/> <dif:Province_or_State/> <dif:Postal_Code/> <dif:Country/> </dif:Contact_Address> </dif:Personnel> </dif:Data_Center>
The ECHO dialect combines people and organizations into the Contact structure:
<Contact> <Role/> <HoursOfService/> <Instructions/> <OrganizationName/> <OrganizationAddresses> <Address> <StreetAddress/> <City/> <StateProvince/> <PostalCode/> <Country/> </Address> </OrganizationAddresses> <OrganizationPhones> <Phone> <Number/> <Type>voice</Type> </Phone> <Phone> <Number/> <Type>fax</Type> </Phone> </OrganizationPhones> <OrganizationEmails> <Email/> </OrganizationEmails> <ContactPersons> <ContactPerson> <FirstName/> <MiddleName/> <LastName/> <JobPosition/> </ContactPerson> </ContactPersons> </Contact>
The ECHO Collection Roles:

The ECS Collection Metadata include eight roles:
Value | Count |
Archive | 4481 |
Data Originator | 594 |
Distributor | 6 |
Instrument | 68 |
Investigator | 851 |
Producer | 3201 |
Quality Assessment | 4 |
User Services | 587 |
The ISO dialect combines people and organizations into the CI_ResponsibleParty object, a flexible structure that supports many combinations of organizations and people. Most objects that include associated responsible parties can have any number, so, for example, a citation can have people identified in any or all of the roles listed in the CI_RoleCode code list.
The structure of the CI_ResponsibleParty is:
<gmd:CI_ResponsibleParty> <gmd:individualName/> <gmd:organisationName/> <gmd:positionName/> <gmd:contactInfo> <gmd:CI_Contact> <gmd:phone/> <gmd:address> <gmd:CI_Address> <gmd:deliveryPoint/> <gmd:city/> <gmd:administrativeArea/> <gmd:postalCode/> <gmd:country/> <gmd:electronicMailAddress/> </gmd:CI_Address> </gmd:address> <gmd:onlineResource/> <gmd:hoursOfService/> <gmd:contactInstructions/> </gmd:CI_Contact> </gmd:contactInfo> <gmd:role/> </gmd:CI_ResponsibleParty>
