@RobLa-WMF, thanks for putting all the links together. I have seen some of
them, and will email the authors.
Row objects vs arrays
---------------------
I feel that other formats are optimized towards parsing and processing,
rather than storage and ease of use. Repeating column names for each row seems
overly verbose, and, in case of raw-text editing, makes it less readable and
harder not to make mistakes. On the other hand, their system benefits sparse
tables - missing values may simply be omitted, whereas in my proposal one would
have to use "null". Also, for some use cases like graphs, parsing would require
an extra step - converting arrays into objects on the client (could be done
with auto-generated code for higher efficiency).
"rows": [
{"column1":"foo", "column2":42, "optColumn3": true}, // rows as objects
{"column1":"bar", "column2":13},
]
"columns": ["column1", "column2", "optColumn3"],
"rows": [
["foo", 42, true], // rows as arrays
["bar", 13, null]
]
Target audience
---------------
Other formats, especially W3C, seem to only target
machine-generation/consumption, and thus become extremely verbose and complex.
They only need very few developers to fully understand and implement them.
While I hope that we will quickly introduce good data editing tools, I think
our format needs to be widely understood on its own by the same community that
uses wiki markup, so that it can be easily consumed by developers of Lua
modules and Graphs.
Data types, constrains, ...
---------------------------
I do not have very strong feelings either way about how to declare data
types. I foresee the basic data types like `number`,`string`,`bool`, plus some
more exotic ones like multi-lingual string (one string per language). Hard to
define types like Wikidata ID, datetime, and URL could be stored as a string
until we can reuse Wikidata's type system. Another needed feature is to reuse
metadata from another page, thus allowing multiple pages to have the same
structure.
