issues

• only on Firefox: Clicking any datasources-toggle (in the bottom-halve) causes the element-height to reset.

• ULS language-selector not reachable via the keyboard.

• Main bookmark links are not reachable via the keyboard.

• Font-type input-element does not allow for keyboard-based font-selection (UP / DOWN).

• Pane-switching: Keyboard access to iframe only works from the core-app to the content-pane but not back (something broke this mechanism).

• TODO: Note all the core-app & embedded-app parts that fail for touch-interactions.

• Backwards & Forwards history navigation has several issues.
  • note: The web standards community is working on improving the browser-history API, since many other “Single Page Applications” (SPA) are running into the same issues.
  • See also: App History API (proposal)

• Reloading complex-encoded URLs does not always work, due the mis-encoding of the URL parameters. This is a tricky issue, for which the causes which will need to be carefully studied, tested and fixed. Research what tools could be used to help debug this issue.
  • There is a need to have a better workflow & tooling to help with debugging these URL-issues.
  • Examples: …
  • related issues:
    • implement geospatial-search query URL serialization and loading

• Add persistent-linking to inline-views
  • When clicked on headline/section fields, set the fragment-parameter in the URL
  • When a URL with a fragment is loaded, upon up the inline-view.
  • Note: Make sure the used IDs are robust and durable.
  • BUG: same ID used multiple times per page. Solution: add field-ID-name to current ID–> update all inline-field-handling code with this prepend:

     for each topic-card:
       <details title="europeana_inline" id="europeana_inline_mv-n00"
       <details title="pexels" id="pexels_mv-n00"
       ...

• URL hash handling
  • Fix the hash-handling conflict between the inline-category widget and Wikipedia ToC clicks.
  • Always reset the hash when needed (eg. when clicking on another topic) (partly fixed)
  • Scroll-position / section alignment issue for Wikipedia (example)

• The SwiperJS library - used for mobile swiping - is an older, somewhat broken version (page hangs occur between animations). The newer version breaks all rendering (for some reason). Todo: Figure out how to upgrade this library correctly.

• Cold-startup time (upon first use) is very slow - sometimes more than 10-20 seconds on low-bandwidth networks.

• The Apple iOS mobile browser needs more UX testing & fixing.

• The Wikipedia-app needs a “Table of Content” system suited for mobile devices.

• Sync (ImmortalDB) state across tabs, after each data change. (work in progress)

• BUG: Update bookmarking system to handle datasource selection (originally only build for links / wikipedia).
• BUG: view boomark URL is wrong? It does not bookmark the search-query?
• BUG: “Villa Park” search –> bookmark view-URL –> quotes not stored in the bookmark (example)

• Implement an async, meta-data result-augmentation workflow. This is used for API-results which need multiple data fetches.

• Geospatial parameters should be re-applied to globe-map upon re-visits and zoomed-in when the globe-map is opened.

• Docker-based local-development mappings are not producing a working Conzept build (some directories are not found / browser-security issues ).

• Cover fetching:
  • Monthly cronjob based fetching not yet implement.
  • The “CONZEPT_PREVENT_COVER_FETCH” option does not work yet.

• Difficulty avoiding duplicate items in more complex/stacked SPARQL queries. There are some ways to contain the issue (GROUP BY), but that is clumsy and it is not possible to generalize to all SPARQL queries. This is a serious limitation, due to the the two-dimensional (tabular) data dimensioning with SPARQL queries (duplicate items, with multiple values for a property, these should be embedded “arrays” within each item).
• Wikidata: claim-statements integration not done yet, because the data-access is more complex when using the “wikibase-sdk” (with claims).
• Abandoned Wikidata-based tools.

• Correctly highlight search-terms with multiple “quoted” phrases.

• Safari/Webkit browsers: GBIF app: country-border-map transform is wrong. Other browser work fine.
