Facet Based Resource Model
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 | ..... |
authorization | 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 | .... |
properties | 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) | |

output | String | ... |
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. |
IP Info Facet
TO BE RENAMED ???
The goal of this facet is to capture IP information
IPAddress | String | ... |
mask | String | ... |
broadcastAddress | String | ... |
Regular expression to validate different IPv4 addresses are available at:
Both IPv4 and IPv6: http://stackoverflow.com/questions/53497/regular-expression-that-matches-valid-ipv6-addresses
License Facet

The goal of this facet is to .....
size | Long | ... |
used | Long | ... |
unit | String | ... |
Peripheral Facet
The goal of this facet is to .....
model | String | ... |
vendor | String | ... |
Persistent Memory Facet
Specialization of Memory Facet
TBD if instead of subclassing is better subclassing ConsistOf relation of reintroduce purpose in relation or header
Provenance Facet
The goal of this facet is to collect information related with resource lineage/provenance
relationship | Enum | wasGeneratedBy | ... |
reference | String | resourceID (a reference to the "originator" Resource associated to the resource the facet is attached to by the relationship) |
provenanceDocument | String | ... E.g. the xml format |
provenanceDocumentSchema | String | ... E.g. a reference to the format |
Simple Property Facet
The goal of this facet is the base class for all facets described by a value and the schema of the value
value | String | ... |
schema | URI | ... |
Software Facet
The goal of this facet is to capture SW related features"
name | String | The name of the software artefact being described. E.g. artifactId in maven, Service Name in gCube software, the software name for retail software Microsoft Office 2013-SP2. |
group | String | The name of "group" the software artefact belongs to. E.g. groupId in Maven, ServiceClass in gCube software, company name for retail software Microsoft Office 2013-SP2. |
version | String | The particular release of the software artefact. E.g. maven version, Service Version in gCube software, artifactId in maven, the software version for retail software Microsoft Office 2013-SP2. |
description | String | A human oriented description of the software artefact being described. |
qualifier | String | E.g. packaging or scope in maven, scope level or sharable level in gCube software, target architecture for retail software x86 or amd64. |
role TO BE REMOVED | String | Identify the role of this facet. E.g. dependency. |
optional | boolean | .... Used in maven and in gcube |
