Introduction

A bit of terminology

ResourceObject

A resource object represents content that is ready-to-use in the Wolfram Language.

In[]:=

ResourceObject["Space Shuttle 3D Model"]

Out[]=

ResourceObject

Name: Space Shuttle 3D Model »
Type: DataResource
Description: 3D test model of a space shuttle



There are two primary benefits to turning content into resource objects.

◼

Attaching Metadata

◼

Distribution

Repository

Repositories are collections of similar resource objects. All resources in a repository share the same:

◼

Type of content

◼

Metadata schema

◼

Website

◼

Integration into the Wolfram Language

Resource System

The resource system is the full collection of technology for use, creation and distribution of resource objects including public repositories deployed to the Wolfram Cloud.

Repositories

◼

Data Repository (2017)

◼

Neural Net Repository (2018)

◼

Function Repository (2019)

◼

Paclet Repository (2022)

Finding Resource Objects

Using Resource Objects

Each repository has its own integration into the Wolfram Language.

Each of these functions is using a ResourceObject from a resource system repository.

In[]:=

ResourceObject/@{"Space Shuttle 3D Model","Wolfram Sentence Splitter Net for TextSentences WL 12.0 V2","Wolfram AudioIdentify V1 Trained on AudioSet Data","BirdSay","Bob/ContentBrowser"}

Details

ResourceObject[“name”] looks for resources at locations along $ResourceSystemPath

In[]:=

$ResourceSystemPath

If it finds a resource remotely it retrieves only the metadata.

In[]:=

rebels=ResourceObject["Paul Revere's Social Network in Colonial Boston"]

Out[]=

ResourceObject

Name: Paul Revere's Social Network in Colonial Boston »
Type: DataResource
Description: Dataset of associations among political groups in colonial Boston 1762 - 1775

The first time you use a resource, the content is downloaded and stored locally for faster subsequent use:
