Real-world stats

This is a collection of stats from my own personal Knowboard workspace. My workspace combines project planning across personal and work tasks, along with many references that I want to save.

I first brought in some existing content from Notion, but at the time of writing, this workspace has evolved over the last ~6 months as Knowboard has taken shape.

Structure

This is a rough outline of how my documents are structured:

• Projects
  • Action items
• Reference
  • Topics — used to categorize references
  • Notes
  • Media — learning materials like videos and articles
  • Entertainment — books, movies, etc.
  • Tools — resources for things like software libraries or applications that may be useful
• Reviews
  • Daily
  • Weekly
  • Monthly

Performance

As my workspace has grown, it’s important to me to keep the experience snappy and responsive. These are averages across my recent usage on a 2020 MacBook Air M1:

• Document size: 43MB
• Memory usage: ~150-200MB
• Initial workspace scan: 8.56s
• Hover latency: 10.8 ms

File types

The vast majority of my files are Markdown documents, though the handful of other data files contain a large number of RDF tuples:

Type	Files	Quads
Markdown docs	1,573	18,077
Data files	6	58,864
Total	1,579	76,941

SPARQL

SELECT ?kind ?files ?quads WHERE {
  {
    SELECT ?kind (COUNT(DISTINCT ?graph) AS ?files) (COUNT(*) AS ?quads) WHERE {
      GRAPH ?graph { ?s ?p ?o }
      BIND(IF(STRENDS(STR(?graph), ".md"), "Markdown docs", "Data Files") AS ?kind)
    } GROUP BY ?kind
  }
  UNION
  {
    SELECT ("Total" AS ?kind) (COUNT(DISTINCT ?graph) AS ?files) (COUNT(*) AS ?quads) WHERE {
      GRAPH ?graph { ?s ?p ?o }
    }
  }
}
ORDER BY (STR(?kind))

Data files

One data file is .yamlld to store common workspace @context which is referenced by the Markdown documents.

The others are Turtle .ttl files for storing schemas and other data

Type	Quads
schema.org	17,826
Workspace shapes & schema	1,168
Calendar 1	527
Other personal data sources 2	39,362

I currently have 15 SHACL Shapes covering my common document types in the workspace with the expected properties.

SPARQL

PREFIX sh: <http://www.w3.org/ns/shacl#>
SELECT (COUNT(DISTINCT ?shape) AS ?shapes)
WHERE {
  { ?shape a sh:NodeShape . } UNION
  { ?shape a sh:PropertyShape . } UNION
  { ?shape a sh:Shape . }
}
