TravelFeed – Modifying Hivemind

6개월 전

Utopian for TravelFeed: is running this task request on behalf of the TravelFeed Project.



We need a modified Hivemind instance to power the GraphQL API of our dApp.

The following modifications need to be made to the Hivemind code (Python):


  • Only include posts with a minimum word count of 250 words and travelfeed in the tags and/or category.

  • Add columns for latitude and longitude extracted from the post's json_metadata. Here is an example TravelFeed post with a location in the json_metadata.

    • Scan the post body for a SteemitWorldMap code snippet (swmregex) if no (valid) "coordinates" field is set in the json_metadata.
    • If none of the above apply, default value is NULL.
  • Add columns for country, subdivision, area, and neighbourhood

    • country (ISO 3166 country code)
    • subdivision (ISO 3166 code for state/province/territory..)
    • area (post code if applicable, otherwise, default to NULL)
    • neighbourhood (for rural areas name of larger region e.g. Black Forest, Outback, Mekong Delta, defaults to NULL if it cannot be determined). All names in English. Use a reverse Geocoding service to obtain these information based on the coordinates. Could be done with GeoPy and Nominatim.
  • Add column for curation_score: Percentage of vote by @travelfeed. Defaults to 0.


  • Add columns for facebook, instagram, youtube, couchsurfing populated from the json_metadata. Default to NULL.


Calls from the API to the Hivemind database include:

  • Location search: Get posts where latitude and longitude is in certain range, possibly sorted by proximity to a given location;
  • Text search: Get posts by full text search;
  • Feeds: Get posts where author / one or multiple tags / country / subdivision / area / neighbourhood matches/contains request; Get posts chronologically for all authors that are followed by a certain user.
  • User search: Get user where location / Steem username / Steem display_name / instagram / facebook / twitter / youtube / couchsurfing ID matches request;
  • Order posts by curation score or chronologically.

@travelfeed we researched what could be a much better location system message me. We had long conversations about what would be the best way to tag posts or images with a location. Let's chat


I'm curious to hear about that, just sent you a message!
