Solid Namespace
A collection of common RDF namespaces used in the Solid project.
solid-namespace can be used with any RDF/JS-compatible library (e.g. rdflib.js).
Usage
You can use this library in two ways.
- With a RDF JS library to get NamedNodes
- Without a library to get url strings
With a rdf library
If a rdf library is provided then the map of namespaces given will be the result of calling $rdf.namedNode on the namespace urls.
const $rdf = require('rdflib');
const ns = require('solid-namespace')($rdf);
const store = $rdf.graph();
let me = ...;
let name = store.any(me, ns.vcard('fn')) || store.any(me, ns.foaf('name'));
console.log(ns.foaf('name')); // -> NamedNode(<http://xmlns.com/foaf/0.1/name>)
Without a rdf library
const ns = require('solid-namespace')();
console.log(ns.foaf('name')); // -> "http://xmlns.com/foaf/0.1/name"
Vocabularies included
The vocabularies included in this repo are endorsed by the Solid leader, and are recommended to use in Solid projects. Below are the vocabularies listed with a short explanation of intent.
| Name | Abbreviation | URL | Description |
|---|---|---|---|
| Basic Access Control ontology | acl | https://www.w3.org/ns/auth/acl# | Defines the class Authorization and its essential properties, and also some classes of access such as read and write. |
| A simple Argumentation ontology | arg | http://www.w3.org/ns/pim/arg# | This ontology may be used to capture the relationship between different [description ends here…] (NEED BETTER DESCRIPTION) |
| NEED NAME | cal | http://www.w3.org/2002/12/cal/ical# | NEED DESCRIPTION |
| Contact: Utility concepts for everyday life | contact | http://www.w3.org/2000/10/swap/pim/contact# | To illustrate with examples the creation of a schema of RDF properties and classes, but using abstract things for people, rather than strings, etc. If you have an "Assistant's phone number", then really you have an assitant who has a phone number - and that is much more useful in general. For example, when data about you and your assietnt in merged, you will end up with an "assistant's email" and the like. |
| DCMI Metadata Terms - elements (CORRECT NAME?) | dc | http://purl.org/dc/elements/1.1/ | NEED DESCRIPTION |
| DCMI Metadata Terms - terms (CORRECT NAME?) | dct | http://purl.org/dc/terms/ | NEED DESCRIPTION |
| Description of a Project (DOAP) vocabulary | doap | http://usefulinc.com/ns/doap# | The Description of a Project (DOAP) vocabulary, described using W3C RDF Schema and the Web Ontology Language. |
| Friend of a Friend | foaf | http://xmlns.com/foaf/0.1/ | FOAF is a project devoted to linking people and information using the Web. Regardless of whether information is in people's heads, in physical or digital documents, or in the form of factual data, it can be linked. FOAF integrates three kinds of network: social networks of human collaboration, friendship and association; representational networks that describe a simplified view of a cartoon universe in factual terms, and information networks that use Web-based linking to share independently published descriptions of this inter-connected world. FOAF does not compete with socially-oriented Web sites; rather it provides an approach in which different sites can tell different parts of the larger story, and by which users can retain some control over their information in a non-proprietary format. |
| HTTP Message Vocabulary | http | http://www.w3.org/2007/ont/http# | This is a vocabulary for describing HTTP messages. |
| HTTP Header Vocabulary | https | http://www.w3.org/2007/ont/httph# | This vocabulary is a one deemed to contain all HTTP headers. The rdflib.js library uses it as for relationships between an HTTP response and the content (value) of the HTTP header in that response. The ontology is deemed to contain one property for every HTTP header, standard or not. The property in this ontology has a localname which is the header field converted to lower case. |
| NEED NAME | icalTZ | http://www.w3.org/2002/12/cal/icaltzd# | NEED DESCRIPTION |
| The W3C Linked Data Platform (LDP) Vocabulary | ldp | http://www.w3.org/ns/ldp# | This document is an HTML representation of OWL ontology describing all vocabulary URIs defined in the Linked Data Platform (LDP) namespace. This ontology provides an informal representation of the concepts and terms as defined in the LDP or other relevant specifications. Consult the LDP specification for normative reference, unless a different specification is indicated inline. See also http://www.w3.org/2012/ldp, http://www.w3.org/TR/ldp-ucr/, http://www.w3.org/TR/ldp/, http://www.w3.org/2011/09/LinkedData/ |
| Ontology for Linked Data | link, tab, tablet | http://www.w3.org/2007/ont/link# | This is a vocabulary for describing relationships between linked data objects and things fetched from the web. |
| NEED NAME | log | http://www.w3.org/2000/10/swap/log# | NEED DESCRIPTION |
| An ontology for an online meeting | meeting | http://www.w3.org/ns/pim/meeting# | An online meeting, in Solid world, is a collection of linked data resources which allow people to collaborate in real time toward the objectives of the meeting. The online state of a meeting may also evolve before the meeting as it is planned, and it should also in time evolve to give a clear idea of the take-aways for posterity |
| Music Ontology | mo | http://purl.org/ontology/mo/ | The Music Ontology Specification provides main concepts and properties fo describing music (i.e. artists, albums and tracks) on the Semantic Web. |
| The OWL 2 Schema vocabulary (OWL 2) | owl | http://www.w3.org/2002/07/owl# | This ontology partially describes the built-in classes and properties that together form the basis of the RDF/XML syntax of OWL 2. The content of this ontology is based on Tables 6.1 and 6.2 in Section 6.4 of the OWL 2 RDF-Based Semantics specification, available at http://www.w3.org/TR/owl2-rdf-based-semantics/. Please note that those tables do not include the different annotations (labels, comments and rdfs:isDefinedBy links) used in this file. Also note that the descriptions provided in this ontology do not provide a complete and correct formal description of either the syntax or the semantics of the introduced terms (please see the OWL 2 recommendations for the complete and normative specifications). Furthermore, the information provided by this ontology may be misleading if not used with care. This ontology SHOULD NOT be imported into OWL ontologies. Importing this file into an OWL 2 DL ontology will cause it to become an OWL 2 Full ontology and may have other, unexpected, consequences. |
| NEED NAME | pad | http://www.w3.org/ns/pim/pad# | NEED DESCRIPTION |
| NEED NAME | patch | http://www.w3.org/ns/pim/patch# | NEED DESCRIPTION |
| An ontology for personal finances | qu | http://www.w3.org/2000/10/swap/pim/qif# | An ontology for data exported, for example, by Quicken, as an interchange format. Also a generally useful ontology for bank transactions. See also the OFX ontology. |
| NEED NAME | trip | http://www.w3.org/ns/pim/trip# | This ontology is for use in describing trips, such as business trips. Trips connect where we are at a given point in time, meetings which are part of the trip, and who pays for the trip or part of the trip. They are useful for describing travel plans, for working out expenses, and for categoizing photographs. Trips do not in fact logically have to involve travel. A trip could be used to collate expenses relating to an activity or event at ones home base, or a set of photos taken at home etc. |

| Workspace Ontology | space | http://www.w3.org/ns/pim/space# | This ontology is for use in describing Workspaces. Workspaces are place where data is stored and asscoiated prolices of privacy. A given application typically stores information in several different workspaces, some being user private, some shared, and some public. It is crucial that the user has easy control over the destiny of information. Goals then are that the user can: - create workspaces - easily understand which workspace data is going into - understand what the implications of that are - (later) set ACLS on them - publish apropriate use policies for them |
| NEED NAME | stat | http://www.w3.org/ns/posix/stat# | NEED DESCRIPTION |
| An ontology for User Interface description, Hints and Forms. | ui | http://www.w3.org/ns/ui# | The User Interface ontology allows the definition of forms for processing RDF model data, and include a bootstrap form for editing forms. It allows user interface hints such as background colors, can be associated with objects and classes. |
