Search engine optimisation, a series of techniques which improve the visibility of a website in search engines result page (SERP) via the natural or unpaid (‘organic’ or ‘algorithmic’) search results. The goal of such optimisation is to rank as high as possible for a certain search query.
An evolution or part of the World Wide Web that consists of machine-readable data in RDF and an ability to query that information in standard ways (e.g. via Sparql).
Statistical data and metadata exchange, an international initiative that aims at standardising and modernising the mechanisms and processes for the exchange of statistical data and metadata among international organisations and their member countries.
Extracting data from a non-machine-readable source, such as a website or a PDF document, and creating structured data from the result. Screen-scraping a dataset requires dedicated programming and is expensive in programmer time, so is generally done only after all other attempts to get the data in structured form have failed. Legal questions may arise about whether the scraping breaches the source website’s copyright or terms of service.
Schema.org is a vocabulary for structured data on the Internet, on web pages, in email messages, etc. It covers entities, relationships between entities and actions, and can easily be extended through a well-documented extension model. Schema.org is developed by W3C Community group in an open community process.
An XML schema defines the structure of an XML document. An XML schema defines things such as which data elements and attributes can appear in a document; how the data elements relate to one another; whether an element is empty or can include text; which types of data are allowed for specific data elements and attributes; and what the default and fixed values are for elements and attributes. A schema is also a description of the data represented within a database.
Software as a Service, i.e. a software program that runs, not on the user’s machine, but on the machines of a hosting company, which the user accesses over the web. The host takes care of associated data storage, and normally charges for the use of the service or monetises its client base in other ways.
A family of web feed formats (often dubbed Really Simple Syndication) used to publish frequently updated works — such as blog entries, news headlines, audio, and video — in a standardized format.
