Decision Matrix Bases View

A custom Obsidian Bases view for weighted decision-making. Score options across criteria, set weights, get ranked results.

Features

  • Two view types — decision-matrix (full scoring table) and decision-matrix-rankings (podium + ranked card list)
  • Inline score editing — click any cell to edit; written back to frontmatter immediately
  • Weighted scoring — per-criterion weights, weighted average, ranked rows with tie detection
  • Blank vs. zero — unset scores display blank; explicit 0 is a deliberate judgment. Both treat as 0 in calculations.
  • Weight pre-fill — add weight_<criterion>: N to the embedding note's frontmatter; weights load on open and reset via the ↺ button
  • Negative weights — penalize criteria; denominator uses Σ|weight| so scale stays consistent
  • Score prefix stripping — set a prefix (e.g. score_) in settings to strip it from display names
  • Rank Raws — per-column checkboxes in the Raw Scores table header row; enable per-criterion to convert that column's raw values into competition ranks before weighted scoring. Useful when criteria are on incompatible scales (e.g. price in dollars vs. quality 1–10). Ranked value is shown prominently with the raw score below for reference.
  • Per-criterion normalization — scales only criteria whose max exceeds the target scale
  • Row grouping — uses Bases native grouping; groups are collapsible
  • Scale toggle — /5, /10, /100

Requirements

Obsidian 1.9.10+ (Bases required)

Installation

Via BRAT: add jortscity/dmatrix-bases-view as a beta plugin.

Setup

Base file

views:
  - type: decision-matrix
    name: My Decision
    filters:
      and:
        - file.folder == "Options"
        - 'file.ext == "md"'
        - file.name != this.file.name
    order:
      - title
      - cost
      - performance
      - quality

Any property in order with numeric values becomes a scoring criterion.

Scores

---
title: Option A
cost: 8
performance: 7
quality: 9
---

Weights

Embed the base in a note and add weight_<criterion> properties:

---
weight_cost: 3
weight_performance: 5
weight_quality: 4
---

![[my-decision.base]]

Weights are session-only. Edit them live in the view, or hit ↺ to reload from frontmatter.

Rankings view

Same setup, different view type:

views:
  - type: decision-matrix-rankings

Add a cover URL property to notes for thumbnail images in the podium cards.
