Coherence and cohesion are dimensions within overall article development that deal with how articles work together to form a more complete picture - concepts that we will be dealing with more and more as new article creation slows down due to our approaching a theoretical concept limit, and we develop a greater focus on developing existing articles and topics to their maximum depth.
There are areas which are well developed: Well formed articles are considered such largely because they deal with and link to the most relevant superordinate (contexts) and subordinate topics (concepts) in a logical order. The liberal usage of topicboxes is a necessity for large series of articles to be coherently navigable and developed.
Coherency refers to an article providing logical, understandable and usable knowledge to the reader. In order to be coherent,
| 1 | the article shall treat one topic, or many topics that are logically related to each other, | otherwise the article is fragmented |
|---|---|---|
| 2 | if many topics are treated, then there shall be text that relate each topic to each other, | otherwise the article is fragmented |
| 3 | the language shall be as easy and straightforward as possible, not making outright deviations from the topic before reaching an explanation, and | otherwise the language is messy |
| 4 | the terms should be as common, as unambiguous and as comprehensible as possible, the terms used mustn't contradict each other, | otherwise the language contains too much jargon |
| 5 | the article layout shall follow the conventional article order in Wikipedia, | because that is the general "layout" of all human communications, |
| 6 | and the article shall neatly integrate, (not contradict, not overlap), into the larger dataset called Wikipedia. | coherency on a larger scale |
Coherency is not about truth and verification. Coherency is about understandability and logic. If there is neither too much nor too little information, and the explanation is simple and clear instead of overflowing with irrelevant details, then the article is coherent!
