Facets
Access Point Facet
The goal of this facet is expected to capture information on “access points” for a resource, i.e. any endpoint to interact with the resource via a known protocol.
| entryName | String | An unique identifier |
| endpoint | URI | The URI which identify the endpoint of a resource |
| protocol | String | The high-level protocol used by the access point. The String could contains the version if needed.
E.g. WMS not http which is already contained in URI. |
| description | String | ..... |
| authorizationValue | String | Contains authorization information. E.g: a token, username:password. By relying on schema it should be sufficient to capture also whether the content is encrypted or not |
| authorizationSchema | URI | .... |
| propertiesValue | String | This can be an arbitrarily complex element whose "structure" is defined by the associated schema |
| propertiesSchema | URI | .... |
Contact Facet
The goal of this facet is expected to capture contact information.
| name | String | TBD Contains Name and Surname maybe also middle name and title (Dr. Mr.) or we add a new fields |
| Valid eMail address | An RFC‑822 compliant email address.
(At http://www.ex-parrot.com/~pdw/Mail-RFC822-Address.html you can find a very complex regular expression for validation) | |
| website | URL | ... |
| address | String | ... |
| phone | String | ... |
Coverage Facet
The goal of this facet is to collect any "extent"-related information.
| spatialValue | String | ... |
| spatialSchema | URI | ... |
| temporalValue | String | ... |
| temporalSchema | URI | ..... |
CPU Facet
The goal of this facet is to describe CPU information. //TODO to be reviewed
| modelName | String | ... |
| vendor | String | ... |
| clockSpeed | String | ... |
Descriptive Metadata Facet
The goal of this facet is to collect any descriptive metadata about the resource.
| value | String | .... E.g. XML Blob |
| schema | URI | ... |
Event Facet
The goal of this facet is to collect any descriptive metadata about the resource.
| type | String | ... |
| typeSchema | URI | ... |
| date | String | ... |
| dateSchema | URI | ... |
Identification Facet
The goal of this facet is to collect information on Identifiers that can be attached to a resource.
| value | String | The identifier. E.g. http://fr.dbpedia.org/resource/Thunnus de305d54-75b4-431b-adb2-eb6b9e546014 |
| type | Enumeration | The typology of identifier. E.g. URI, DOI, IRI, URL, URN, UUID; |
| isPersistent | boolean | To indicate if the Identifier is persistent or not. |
Relations
The following relations (extending the relatedTo) have been identified and defined:
- callsFor: Service to Service
- dependsOn: Software to Software
- managedBy: Hosting Node to Site
- manages: Service to Dataset
- poweredBy: Hosting Node to Software
- requires: Software to Service
Resource Profiles
The following resources have been identified:
- Actor
- Configuration
- Dataset
- Concrete Dataset
- Service
- Abstract Service
- E-Service
