A StatisticalPopulation is a set of instances of a certain given type that satisfy some set of constraints. The property populationType is used to specify the type. Any property that can be used on instances of that type can appear on the statistical population. For example, a SEO.JSONLD.StatisticalPopulation representing all SEO.JSONLD.Persons with a homeLocation of East Podunk California would be described by applying the appropriate homeLocation and populationType properties to a SEO.JSONLD.StatisticalPopulation item that stands for that set of people. The properties numConstraints and constraintProperty are used to specify which of the populations properties are used to specify the population. Note that the sense of "population" used here is the general sense of a statistical population, and does not imply that the population consists of people. For example, a populationType of SEO.JSONLD.Event or SEO.JSONLD.NewsArticle could be used. See also SEO.JSONLD.Observation, where a populationType such as SEO.JSONLD.Person or SEO.JSONLD.Event can be indicated directly. In most cases it may be better to use SEO.JSONLD.StatisticalVariable instead of SEO.JSONLD.StatisticalPopulation.

SEO.JSONLD.StatisticalVariable represents any type of statistical metric that can be measured at a place and time. The usage pattern for SEO.JSONLD.StatisticalVariable is typically expressed using SEO.JSONLD.Observation with an explicit populationType, which is a type, typically drawn from Schema.org. Each SEO.JSONLD.StatisticalVariable is marked as a SEO.JSONLD.ConstraintNode, meaning that some properties (those listed using constraintProperty) serve in this setting solely to define the statistical variable rather than literally describe a specific person, place or thing. For example, a SEO.JSONLD.StatisticalVariable Median_Height_Person_Female representing the median height of women, could be written as follows: the population type is SEO.JSONLD.Person; the measuredProperty height; the statType median; the gender Female. It is important to note that there are many kinds of scientific quantitative observation which are not fully, perfectly or unambiguously described following this pattern, or with solely Schema.org terminology. The approach taken here is designed to allow partial, incremental or minimal description of SEO.JSONLD.StatisticalVariables, and the use of detailed sets of entity and property IDs from external repositories. The measurementMethod, unitCode and unitText properties can also be used to clarify the specific nature and notation of an observed measurement.

A suite in a hotel or other public accommodation, denotes a class of luxury accommodations, the key feature of which is multiple rooms (source: Wikipedia, the free encyclopedia, see http://en.wikipedia.org/wiki/Suite_(hotel)).

Anatomical features that can be observed by sight (without dissection), including the form and proportions of the human body as well as surface landmarks that correspond to deeper subcutaneous structures. Superficial anatomy plays an important role in sports medicine, phlebotomy, and other medical specialties as underlying anatomical structures can be identified through surface palpation. For example, during back surgery, superficial anatomy can be used to palpate and count vertebrae to find the site of incision. Or in phlebotomy, superficial anatomy can be used to locate an underlying vein; for example, the median cubital vein can be located by palpating the borders of the cubital fossa (such as the epicondyles of the humerus) and then looking for the superficial signs of the vein, such as size, prominence, ability to refill after depression, and feel of surrounding tissue support. As another example, in a subluxation (dislocation) of the glenohumeral joint, the bony structure becomes pronounced with the deltoid muscle failing to cover the glenohumeral joint allowing the edges of the scapula to be superficially visible. Here, the superficial anatomy is the visible edges of the scapula, implying the underlying dislocation of the joint (the related anatomical structure).

For the case of a single file published after Zip compression, the convention of appending '+zip' to the encodingFormat can be used.

WebContent is a type representing all SEO.JSONLD.WebPage, SEO.JSONLD.WebSite and SEO.JSONLD.WebPageElement content. It is sometimes the case that detailed distinctions between Web pages, sites and their parts are not always important or obvious. The SEO.JSONLD.WebContent type makes it easier to describe Web-addressable content without requiring such distinctions to always be stated. (The intent is that the existing types SEO.JSONLD.WebPage, SEO.JSONLD.WebSite and SEO.JSONLD.WebPageElement will eventually be declared as subtypes of SEO.JSONLD.WebContent.)

A web page. Every web page is implicitly assumed to be declared to be of type WebPage, so the various properties about that webpage, such as breadcrumb may be used.
