Issues × traditions

Which communities answered which questions, and when. Each cell counts the works whose main design issue is the row and whose tradition is the column, with the year of the earliest; open a cell for the works themselves. Blank cells are questions a tradition has not taken up, or that this catalogue has not yet covered.

Technical Questions a specification or better engineering could settle: what the data is, and how it is handled.
Representation How things are named, connected, shaped and written down.

Reasoning What follows from it?		171959		102009	51999	42003							21970					27

Bridge Technical machinery for a social agreement: the languages for defining terms can be specified, but the terms themselves have to be agreed.
Vocabulary What terms do we share?		161985	22007	11985	241995	32011	102000	12009	22017	181876	51987	82004	32003	32008	31984	21998	42015	69
Human Questions that persist even with a perfect specification, because they depend on behaviour, incentives or power: who, not how.
Institutional Who hosts it, who vouches for it, and who decides.
Topology Where does data live, and who hosts it?					42010		62007		161964									17
Trust Who vouches for it?		12005			81996	11998			51991		22010	12021	12024					14

Economic Whether running it makes sense, commercially or as a public good: who uses it, who pays, and what it costs people to work with.
Adoption & incentives Why would anyone publish or use it?					22007	32001												5
Sustainability Who pays for it, and for how long?					11995	12016	12003	42001		41995		12003	21978					9

Counts use each work's main design issue only; a work in several traditions counts in each. The year is the earliest dated work in the cell. Works that span every issue (the Semantic Web vision itself) and people and organizations are not counted. Each group's all row also gives the share of a tradition's works that fall in that group.
