Creating standard REST APIs to connect data

Achieving the Digital Thread

Use OSLC to connect your data and achieve the digital thread across domains, applications, and organizations

Inspired by the Web

Transition from a world of incompatible systems into a world of connected data

Before the Web

There were many hypertext systems. Those systems had no compatibility to one another. They also used different protocols to access and connect the documents. Documents in System Type 1 could not link to documents in System Type 2.

After the Web

HTML became the standard to represent and connect documents. HTTP became the standard protocol to access documents. Documents can be linked independent of their physical location.

Key Concepts of OSLC

Difference between Web of documents, as we use today, and Web of data, as enabled by OSLC

The Web of Documents

The Web uses documents, represented in HTML, to define web pages. Documents on the Web use URLs as identifiers
(URL represented by )

The Web of Data

The Web uses data, represented in RDF, to define data in the Web. Data on the Web use URLs as identifiers
(URL represented by )

Clients can request documents from Servers via a common protocol, HTTP

Clients can request data from Servers via a common protocol, HTTP

Documents from different sources can link to one another by referencing the other document's URL

Data from different sources can link to one another by referencing the other data's URL

Clients can use mashup applications to interact with documents in the Web (Search, Visualize, Analyze, etc)

Google Search, Mozilla Firefox, Google Analytics

OSLC Benefits

Here's how OSLC can empower you

No Vendor Lock-In

Free yourself from vendor dependancy. Your data in your hands


Reuse existing OSLC REST APIs supported by major vendor and for specific application or data formats

Application Integration

Integrate your own or existing open sources applications to visualize, search, analyze and edit your data, and more!

Source Independent

Integrate databases from different sources

Database Independent

Integrate systems with different technologies and standards

Linked Data

Link your data using widely adopted web stardards

Data Visualization

Visualize your data the way you need. Graphs, Tables, Trees, you name it

Data Analysis

Analyze your connected data for insights never before possible

Make Better Decisions

Take action with information and insight never possible before


The OSLC Core Specification is a Hypermedia API standard currently mainly adopted in software and systems engineering domains, but with the potential to provide value to any domain with data integration challenges. The OSLC Core specifications expands on the W3C LDP capabilities, to define the essential and common technical elements of OSLC domain specifications and offers guidance on common concerns for creating, updating, retrieving, and linking to lifecycle resources.

OSLC domain-specific specifications define the equivalent of schemas in RDF for enabling data interoperability. They consist of RDF vocabularies and OSLC resource shapes. RDF vocabularies are used to describe standardized resource types and properties. OSLC resource shapes are used to define constraints such as multiplicity constraints on properties of specific resource types.

Short summary Migration to Github is complete; Lyo now supports JSON-LD and Turtle; Lyo Designer generates OpenAPI/Swagger docs and adds modelling support for SHACL shapes. Lyo 2.4 is expected to be the last 2.x release. We also make a switch to a better changelog convention. ✨ Added JSON-LD support has been added to Lyo Core. Thanks to Ricardo Javier Herrera Ledesma from Koneksys for his effort! Lyo Designer now allows modelling SHACL shapes.
