MoSCoW (must-have, should-have, could-have, won't have)

Originally an issue by @a-kohlhase from the Workshop on Mathematical Data, Cernay 2019.

MUST-Haves

• [x] Description Z/4Z not clear

• [x] filter f(3) is missing

• [ ] Too many clicks before seeing results:

  1. select filter
  2. edit filter variable
  3. ENTER or clicking check icon
  4. clicking "Display results" button
  5. The minus-symbol not so clear

• [ ] Results found:

  • Mismatch with list
  • initialize result list when updating this field

• [ ] "Display results" button should be automatically changed to "Update results" button, if the two-step process is kept up

• [ ] Default column order unclear

• [ ] Default row order insensible

• [ ] Default filter order? Lexicographic

• [ ] Default data set order

• [ ] Status of selected option for Boolean filters unclear

• [ ] Default value for filter "invertible" should be set to true

• [ ] Export to Gap, Sage, Excel/CVS (all, checkboxes)

• [ ] Information about data set

• [ ] font choice too small, color of text not very high in contrast

• [ ] Instead of Home-Button (which functionality is already done via logo) create Contact-Button for creating the owners of the MathDataHub website

• [ ] column names in "choose cols" do not correspond with actual col names

• [ ] column headers should be left-aligned

• [ ] grid structure in table should be clearly visualized

• [ ] finished Boolean filter set to true not identifiable as identical with filter name

• [ ] After having chosen a filter, the focus should go to the editable variables for that filter

SHOULD-Haves

• [ ] search filters (with autocompletion)

• [ ] filters are added via logical AND: extend this via

  • OR, IF, NEGATION, Parenthesis, equality
  • OR, IF, ODD, EVEN, positive (case-insensitive)
  • AND (which is typical case), subconditions like f(0)=f(1) or direct SQL-Queries (like Wikipedia formulae rendered and in LaTeX)

• [ ] enable customizable nested ordering in results

• [ ] search data sets (with autocompletion)

• [ ] pagination option misses out on option "all"

• [ ] "filter" should be replaced by "conditions"

• [ ] Select filter area was clicked

• [ ] Choose columns:

  • Cancel button confusing
  • didn't grab selected columns to available columns
  • didn't change col width
  • didn't try to change the order
  • "choose", "select", "available" all related, but differently named (suggestion: use visibility aspect)

• [ ] too much scrolling space in results list

• [ ] The finished filter variables should be clickable and open their edit-interface;

• [ ] allow to enter more filter specifications (like 0<f(0)<3) at the same time

• [ ] small (hover, click on ?-icon) tooltip information and link for

  • definition
  • example
  • How-to-use-it
  • related filter (e.g. for invertible the filters injective and surjective)

• [ ] responsive design: showing only (positioning) after having selected filters

• [ ] Order of filter entries could determine sorting order of rows

• [ ] author should be able to set the order for filters

• [ ] sampling (randomly) a small set for export

• [ ] English as lingua franca not enough, but maybe "easy solution" via autocompletion list with multilingual entries

• [ ] With caution (privacy issues if published on a general base --> "Make public" button needed): MathDataHub as a community tool

  • with recommender system,
  • contact other people interested in this combination of filters for dataset
  • contact author of data set directly or indirectly (possibly providing own eMail address), e.g. to inform about a missing case

• [ ] Show-Checkboxes

• [ ] Annotation tool for filters, combination of filters

• [ ] Quality of data sets marked via stars/thumbs-up/…

• [ ] Make use of semantics of lists for applying filters, e.g. apply a filter to the second entry in a list

• [ ] tagging data-sets

• [ ] session history

WONT-Haves

• [ ] Instead of f(0), f(1), f(2): f(<…>)
