measurementTechnique	DataCatalog  or DataDownload  or Dataset  or Observation  or PropertyValue  or StatisticalVariable	A technique, method or technology used in an Observation, StatisticalVariable or Dataset (or DataDownload, DataCatalog), corresponding to the method used for measuring the corresponding variable(s) (for datasets, described using variableMeasured; for Observation, a StatisticalVariable). Often but not necessarily each variableMeasured will have an explicit representation as (or mapping to) an property such as those defined in Schema.org, or other RDF vocabularies and "knowledge graphs". In that case the subproperty of variableMeasured called measuredProperty is applicable. The measurementTechnique property helps when extra clarification is needed about how a measuredProperty was measured. This is oriented towards scientific and scholarly dataset publication but may have broader applicability; it is not intended as a full representation of measurement, but can often serve as a high level summary for dataset discovery. For example, if variableMeasured is: molecule concentration, measurementTechnique could be: "mass spectrometry" or "nmr spectroscopy" or "colorimetry" or "immunofluorescence". If the variableMeasured is "depression rating", the measurementTechnique could be "Zung Scale" or "HAM-D" or "Beck Depression Inventory". If there are several variableMeasured properties recorded for some given data object, use a PropertyValue for each variableMeasured and attach the corresponding measurementTechnique. The value can also be from an enumeration, organized as a MeasurementMetholdEnumeration.

To discourage over-use, and reflecting intial usecases, the property is expected only on Product and Offer, rather than Thing. The general trend in web technology is towards responsive design in which content can be flexibly adapted to a wide range of browsing environments. Pages and sites referenced with the long-established url property should ideally also be usable on a wide variety of devices, including mobile phones. In most cases, it would be pointless and counter productive to attempt to update all url markup to use mobileUrl for more mobile-oriented pages. The property is intended for the case when items (primarily Product and Offer) have extra URLs hosted on an additional "mobile site" alongside the main one. It should not be taken as an endorsement of this publication style.
model	Product	The model of the product. Use with the URL of a ProductModel or a textual representation of the model identifier. The URL of the ProductModel can be from an external source. It is recommended to additionally provide strong product identifiers via the gtin8/gtin13/gtin14 and mpn properties.

negativeNotes	Product  or Review	Provides negative considerations regarding something, most typically in pro/con lists for reviews (alongside positiveNotes). For symmetry In the case of a Review, the property describes the itemReviewed from the perspective of the review; in the case of a Product, the product itself is being described. Since product descriptions tend to emphasise positive claims, it may be relatively unusual to find negativeNotes used in this way. Nevertheless for the sake of symmetry, negativeNotes can be used on Product. The property values can be expressed either as unstructured text (repeated as necessary), or if ordered, as a list (in which case the most negative is at the beginning of the list).

Ideally the taxonomy should be identified, and both the textual label and formal code for the category should be provided. Note: for historical reasons, any textual label and formal code provided as a literal may be assumed to be from O*NET-SOC.
occupationalCredentialAwarded	Course  or EducationalOccupationalProgram	A description of the qualification, award, certificate, diploma or other occupational credential awarded as a consequence of successful completion of this course or program.

In the case of a Dataset it will typically indicate the relevant time period in a precise notation (e.g. for a 2011 census dataset, the year 2011 would be written "2011/2012").
