RDFa 1.1 Errata

Introduction

This document records errata and corrections suggested by the community in the RDFa specifications as published on the 7 June 2012:

  1. Errata for RDF Core 1.1
  2. Errata for RDF Lite 1.1
  3. Errata for XHTML+RDFa 1.1
  4. Errata for RDFa 1.1 Primer

These corrections have no normative status as they have not been incorporated in the specification through the Recommendation Track process. Ivan Herman, Semantic Web Activity lead, is the editor of this document. If you find something in one of the documents listed above that you believe may be an error and wish to have it recorded here, please post your discovery to the public-rdfa mailing list, cc-ing to the editor of this document, Ivan Herman. The community has the possibility to react on the post and, typically after 5-6 business days and unless the community strongly objects for the discovery to be recorded as an official erratum, the entry is added to this list by the editor.

The errata are separated into three sections, corresponding to the three parts of the specification.

Three kinds of changes are highlighted: new, added text and deleted text.

Syntax typos in the examples for lists

In RDFa 1.1 Primer in section 2.2.3, 2nd, 3rd, and 4th examples, the closing element should be ul, instead of li.

See the error report

Note on the prefix declaration and the character encoding

The Note right before section 2.1.4.1 does not take into account the possible effect of the HTTP header (and the number 512 is also wrong). Also, in some cases the processor may process the document even if the character encoding declaration is further down the line but if it gets it within a given amount of time from the server. A possible replacement could be:

An important issue may arise if the html element contains a large number of prefix declarations. Encoding issues may arise on documents whose character encoding is not set by the transport layer. The character encoding (i.e., UTF-8, UTF-16, ASCII, etc.) used for an HTML5 file is declared using a meta element in the header in the head element. In HTML5 this meta declaration must fall within the first 5121024 bytes of the pagedocument to surely have an effect, or the HTML5 processor (browser, parser, etc.) will may try to detect the encoding using some heuristics. A very "long" html tag may therefore lead to problems. One way of avoiding the issue is to place most of the prefix declarations on the body element. Another way is to set the character encoding via the HTTP respionse’s Content-Type header.

Typo in Section 2.2.1

In the text after the second example in section 2.2.1: "while maintaining an ambiguousunambiguous content".

See the error report

Typo in Section 2.2.3

In the text after the fourth example in section 2.2.3: "in setting the the context".

See the error report

Added note on the usage of the @vocab attribute

The following paragraph (styled as a note) should be added right before section 2.1.1.4:

The vocab attribute references structured data vocabularies, identified using URLs. RDFa does not limit the form of these URLs or the document formats accessible by de-referencing them; however users SHOULD aim to use widely shared, conventional values for identifying such vocabularies, following conventions of case, spelling etc. established by their publishers.

See the error report.
