從其他相關詞彙中的類和屬性中作了廣泛的擴展，起到膠水作用，但本身也定義了一些類和屬性。
主要涉及作者和讀者。
作者要從讀者讀取反饋，引用，和訂正。三種模型有
核心詞彙爲dcat:Dataset
duv:Feedback繼承自oa:Annotation（web annotation）
web annotation模型中用motivation描述annotation的角色。
duv:Feedback中有一屬性oa:motivated_by，聯繫motivation和feedback。
web annotation其實是資源描述（註解）的通用辦法，也可以用來描述duv:dataset（超出這範圍了）。
以下爲爲一總結。
舉幾個例子：
Example 1 - Usage: A 2-D charting application developed to create temperature plots that consumes temperature readings from a dataset to produce the plot.
Example 2 - Feedback: Laufer provides feedback about the temperature readings dataset.
Example 3 - Citation: A technical report :paperA identified by a DOI cites the dataset. The :dataset-03312013 is also identified by a digital object identifier (DOI).
關於RDF 1.1 N-triples
triple的production爲subject+predicate+object
N-triple的production爲
| [1] | ntriplesDoc |
::= | triple? (EOLtriple)*
EOL? |
| [2] | triple |
::= | subjectpredicate
object '.' |
| [3] | subject |
::= | IRIREF|
BLANK_NODE_LABEL |
| [4] | predicate |
::= | IRIREF |
| [5] | object |
::= | IRIREF|
BLANK_NODE_LABEL|
literal |
| [6] | literal |
::= | STRING_LITERAL_QUOTE ('^^'IRIREF
| LANGTAG)? |
並且定義了新media: application/n-triples
Turtle parser不需要爲n-triple添加輔助性的parsing directive.
RDF graph represented by an N-Triples document contains exactly each triple matching the N-Triplestriple production.
IRIs (internationalized resource identifier )may be written only as absolute IRIs. IRIs are enclosed in '<' and '>' and may contain numeric
escape sequences (described below). For example <http://example.org/#green-goblin>.
IRI作爲標識符
N-Triples是一種通用的assertion語言，對給定數據進行評估得出更多assertion，最終解析出IRI。
要考慮解析的安全問題。
斷言式語言如SAML（安全斷言標記語言）。
