- https://en.wikipedia.org/wiki/DMOZ - from directory.mozilla.org, an earlier domain name) was a multilingual open-content directory of World Wide Web links.It was owned by AOL (now a part of Verizon's Oath Inc.) but constructed and maintained by a community of volunteer editors. DMOZ used a hierarchical ontology scheme for organizing site listings. Listings on a similar topic were grouped into categories which then included smaller categories. DMOZ closed on March 17, 2017 because AOL no longer wished to support the project. The website became a single landing page on that day, with links to a static archive of DMOZ, and to the DMOZ discussion forum, where plans to rebrand and relaunch the directory are being discussed.

- The WELL - a cherished destination for conversation and discussion. It is widely known as the primordial ooze where the online community movement was born — where Howard Rheingold first coined the term “virtual community.” Since long before the public Internet was unleashed, it has quietly captivated some accomplished and imaginative people. Over the last three decades, it’s been described as “the world’s most influential online community” in a Wired Magazine cover story, and ” the Park Place of email addresses” by John Perry Barlow. It’s won Dvorak and Webby Awards, inspired songs and novels, and almost invisibly influences modern culture. Founded more than two decades ago in association with the Whole Earth Review, the service was recently purchased to be run by a group of its own long term active members. The outpouring of support confirmed that The WELL continues to cast a long cultural shadow. Not quite underground, though sometimes under the radar, for many people it’s a place you aren’t quite sure you’ve heard of, but suspect that you wish you had. For members, it’s the place to come up with the next interesting thing. Ultimately, it becomes a way to live.

- https://en.wikipedia.org/wiki/Units_of_measurement - a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same quantity. Any other value of that quantity can be expressed as a simple multiple of the unit of measurement. For example, length is a physical quantity. The metre is a unit of length that represents a definite predetermined length. When we say 10 metres (or 10 m), we actually mean 10 times the definite predetermined length called "metre". The definition, agreement, and practical use of units of measurement have played a crucial role in human endeavour from early ages up to this day. Different systems of units used to be very common. Now there is a global standard, the International System of Units (SI), the modern form of the metric system.
In trade, weights and measures is often a subject of governmental regulation, to ensure fairness and transparency. The International Bureau of Weights and Measures (BIPM) is tasked with ensuring worldwide uniformity of measurements and their traceability to the International System of Units (SI).
- https://en.wikipedia.org/wiki/Metrology - the science of measurement. It establishes a common understanding of units, crucial in linking human activities. Modern metrology has its roots in the French Revolution's political motivation to standardise units in France, when a length standard taken from a natural source was proposed. This led to the creation of the decimal-based metric system in 1795, establishing a set of standards for other types of measurements. Several other countries adopted the metric system between 1795 and 1875; to ensure conformity between the countries, the Bureau International des Poids et Mesures (BIPM) was established by the Metre Convention. This has evolved into the International System of Units (SI) as a result of a resolution at the 11th Conference Generale des Poids et Mesures (CGPM) in 1960.
Metrology is divided into three basic overlapping activities. The first being the definition of units of measurement, second the realisation...ic or fundamental metrology, which is concerned with the establishment of units of measurement, Applied, technical or industrial metrology, the application of measurement to manufacturing and other processes in society, and Legal metrology, which covers the regulation and statutory requirements for measuring instruments and the methods of measurement.
In each country, a national measurement system (NMS) exists as a network of laboratories, calibration facilities and accreditation bodies which implement and maintain its metrology infrastructure. The NMS affects how measurements are made in a country and their recognition by the international community, which has a wide-ranging impact in its society (including economics, energy, environment, health, manufacturing, industry and consumer confidence). The effects of metrology on trade and economy are some of the easiest-observed societal impacts. To facilitate fair trade, there must be an agreed-upon system of measurement.
