Projects

Project proof points replace the deprecated grants indicator. Each record is an indexed project (for example CORDIS) with status, program, dates, and cost fields.

Typical Questions

Which grant projects are tied to this topic?
Is project volume increasing across the chosen window?
How much capital (totalCost / cordisEcContribution) is associated with matching projects?

Type-specific filters

On top of the shared proof-point fields:

statuses — for example ongoing or closed
acronyms
programs — fp7, horizon_2020, horizon_europe
cordisGrantDois
activeDuring — optional activity-window overlap on startField / endField (missing end is ongoing). Body start / end still filter published date.

Time series

Published-date histogram. Optional activeDuring only restricts which projects are counted.

{
  "topicQuery": "11111111-1111-1111-1111-111111111111",
  "resolution": "month",
  "start": "2022-01-01T00:00:00Z",
  "end": "2024-12-31T23:59:59Z"
}

Activity time series

Buckets follow activeDuring.start / activeDuring.end. amountFields are tried in order (first positive value wins).

{
  "topicQuery": "11111111-1111-1111-1111-111111111111",
  "resolution": "month",
  "activeDuring": {
    "start": "2022-01-01T00:00:00Z",
    "end": "2024-12-31T23:59:59Z",
    "startField": "start_date",
    "endField": "end_date"
  },
  "amountFields": ["total_cost", "cordis_ec_contribution"]
}

Each project can include status, acronym, program, startDate, endDate, totalCost, cordisEcContribution, and cordisGrantDoi. Regular time series returns labels and counts by published date. Activity time series also returns amount: capital prorated by how much of the project interval sits in each bucket (amountFields, or 1 per project if omitted).
