Class Method Details

.detect(sample) ⇒ Boolean

Sample detection to see if it matches RDFa (not RDF/XML or Microdata)

Use a text sample to detect the format of an input file. Sub-classes implement a matcher sufficient to detect probably format matches, including disambiguating between other similar formats.

Parameters:

  • sample (String)

    Beginning several bytes (~ 1K) of input.

Returns:

  • (Boolean)
