Preface to the fourth edition
Some attention has been given to the role of tagcoding in overcoming the polarizing forces of social media.
The #xy2wiki engagement step was added between the #tagcoding and #tag2wiki steps to highlight the need in any language of a basic wiki explaining all tagcoding topic dimensions, and providing tools for topic-tag search across those dimensions.
For English, the #en2wiki wiki is part of the Ens Wiki (http://www.ens.wiki/) which may be considered the English language archetype of an xy2.wiki. As ens-dictionary urls in the third edition became obsolete, they have been replaced by ens.wiki urls in this edition.
After the articulation of the #xy2wiki programme, during 2021 a small team has progressed for these other languages: Spanish (http://es2.wiki), French (http://fr2.wiki), Chinese (simplified) (http://zh2.wiki), Russian (http://ru2.wiki), Arabic (http://ar2.wiki), German (http://ger.wiki), Japanese (http://ja2.wiki), Hindi (http://hi2.wiki), Swahili (http://swa.wiki), Telugu (http://te2.wiki), Dutch (http://nl2.wiki), Tagalog (http://tgl.wiki) and Hiligaynon (http://hil.wiki). Native speakers of any of the former languages, Bangla (http://bn2.wiki), Hausa (http://hau.wiki), Indonesian (http://id2.wiki), Portuguese (http://por.wiki), Punjabi (http://pa2.wiki), Turkish (http://tur.wiki) or Urdu (http://urd.wiki) are invited to launch additional translation and wiki-editing efforts.
During the two years of the #covid19 pandemic, one kind of #tagcoding hashtag has increasingly been adopted: it is the combination of #covid19, globally with the ISO country code, and in the US with the state name’s abbreviation. On a global platform such as Twitter the use of two different conventions leads to homonyms: is #covid19CA for Canada or California, and #covid19IL for Israel or Illinois? These and similar homonyms will discourage individual adopters. Homonyms show the need for a global tag localization convention that avoids them. In the chapter on Territorial Tags such a convention is proposed: for California, the #covid19 localization tag is #covid19US06, and for Illinois, it is #covid19US17.
My special gratitude goes to Jeaneth Trivilegio who has been creating the content for Tagalog (http://tgl.wiki) and Hiligaynon or Ilonggo (http://hil.wiki), her mother tongue. Note that no translation software is available for Ilonggo.
