Statistics

Count the elements, their documentation, mappings and languages, and the imports. Returns a SchemaStats of model/schema-stats.yaml.

Usage

CLI

ohi get w3c/prov-o
ohi linkml to stats --pruning-mode skip prov-o.linkml.yaml

Python

import ohi_linkml

with ohi_linkml.load_file("prov-o.linkml.yaml") as schema:
    result = schema.stats(pruning_mode="skip")

JavaScript

import { readFileSync } from "node:fs";
import { LinkML } from "@neverblink/linkml";

const yaml = readFileSync("prov-o.linkml.yaml", "utf8");
const { view, report } = LinkML.loadFromString(yaml, {});
if (!view) throw new Error(JSON.stringify(report));
const result = view.stats({ pruning_mode: "skip" });

Scala

import eu.neverblink.linkml.generator.options.*
import eu.neverblink.linkml.generator.stats.StatsGenerator
import eu.neverblink.linkml.schemaview.{SchemaIssues, SchemaView}

val loaded = SchemaView.loadSchemaViewFromUri("prov-o.linkml.yaml")
given SchemaView = SchemaIssues.orThrow(loaded)
val result = StatsGenerator().generate(
  StatsGeneratorOptions(pruningMode = PruningMode.Skip),
)

C

#include <stddef.h>
#include "ohi_linkml.h"

linkml_init_threads();
char *report = NULL, *error = NULL;
long long schema =
    linkml_load_file("prov-o.linkml.yaml", NULL, &report, &error);
char *result = linkml_stats(
    schema,
    "{\"pruning_mode\": \"skip\"}",
    &error
);
linkml_free(result);
linkml_free(report);
linkml_free(error);
linkml_close(schema);

Try it in the playground, with PROV-O

Options

pruning_modePruningModedefault schema

CLI --pruning-modeScala pruningMode

The elements in scope for the counts.

• tree_root The elements reachable from the tree root class. Without a tree root, the same as schema.
• schema Everything defined in the root schema, and every element reachable from it. This leaves out the unused parts of imported schemas, such as most of linkml:types.
• skip Every element of the root schema and of all its imports.

tree_rootstring

CLI --tree-rootScala treeRoot

The class to use as the tree root, instead of the class with tree_root: true in the schema. Only for the tree_root pruning mode.
