All,

Quick FYI re. installation notes for deploying our 100% Javascript based
RDF Editor using Node.js:

1. Download RDF Editor Zip Archive from:
http://opldownload.s3.amazonaws.com/uda/vad-packages/7.2/rdf_editor_pkg.zip
2. Extract archive to a folder ({RDF Editor Archive Extraction Folder}
henceforth)
3. From your OS command-line interface run: npm install http-server -g 
-- to setup global invocation of HTTP Server
4. From your OS command-line interface run: http-server {RDF Editor
Archive Extraction Folder}/rdf-editor [options]
5. Open up your browser and goto: http://localhost:8080.

Metaphor:

You have entity->attribute->value or subject->predicate->object based
sentences/statements written to a document (identified by a URL).
Entity, Attribute, and Value (optionally) identified by an HTTP URI
(absolute or relative). Likewise, Subject, Predicate, and Object
(optionally) identified by an HTTP URI (absolute or relative).
Sentence/Statement collections are grouped by Attribute (Predicate), and
this is the basis for optimistic concurrency hashes contructed in
regards to multi-user editing actvitity occurring on the same document.

To summarize, as is the case in the real-word:

1. You write sentences to a document (e.g. a page in a book)
2. Sentences in a page are grouped by paragraphs -- the editor uses
statement attributes (predicates) grouping to emulate this concept
3. a document [named graph when writing to SPARQL server] could be part
of a collection -- like one of many pieces of paper in a folder .

Actual document storage is driven by WebDAV, LDP, SPARQL Graph Protocol,
or SPARQL 1.1 INSERTs.

Features:

1. Shared Ontology / Vocabulary Import
2. Intelligent determination of sentence predicate types driven by 
Ontologies / Vocabularies lookups
3. A variety of editing views scoped to Statements, Entities, Attribute
Names, and Attribute Values -- you can toggle across these subject to
your editing modality preferences
4. Allows you download documents to local or cloud storage
5. Cloud Storage supports multiple HTTP-based storage protocols (WebDAV,
LDP, SPARQL Graph Protocol, SPARQL 1.1 INSERT)
6. Deployable using Nodes.js, Apache, IIS, Virtuoso HTTP Server, any
other HTTP Server
7. 100% Javascript based
8. Available in Open Source form.

Enjoy!
