Design Guidelines

LOGO DOWNLOAD

Introduction

"Open Data Spaces (ODS)" is an open and scalable foundation for distributed data management across enterprises and industries, built on organizational and national diversity by design.
These guidelines outline the principles for proper and effective use of ODS brand language and the ODS logo, which symbolizes our core design philosophy. By understanding the intent behind each element and maintaining a consistent visual identity, we aim to build deep trust with our users and partners.
We hope that all stakeholders who use ODS will proudly embrace this brand language and logo as a shared identity, working together to realize a truly open data society.

Logo Origin

Diagram showing the construction of the ODS logo. The mark is derived from the DPQM dual-layer structure and combines geometric forms with modern typography to create the final logo design.

At the core of the ODS logo lies the dual structure of our defining technical feature: the Double Product Quanta Model (DPQM). This design elevates the geometric beauty of the ODS architecture—which effectively separates "data structure" from "data meaning"—into modern, sophisticated typography.

Precision Engineering and Timeless Design

Construction grid of the ODS logotype. The design is based on carefully defined proportions and geometric alignment to ensure readability, consistency, and a timeless visual identity.

Built on a foundation of inclusive neutrality that honors diversity, the logo’s geometric balance features a minimalist, monotone composition stripped of all unnecessary ornamentation. This ensures its credibility as a timeless, enduring standard.

It delivers a highly modern brand experience designed to convey a consistent message across all media.

Logo Clearance and Sizing

Logo usage guidelines showing the required clear space around the ODS logo, based on the height of the “O” symbol, and the recommended minimum size of 30 mm or 300 px in width.

The clear space surrounding the logo must be equal to or greater than the height of the letter "O" in the logo mark on all four sides (top, bottom, left, and right).
The recommended minimum size is a width of 30 mm for print and 300 pixels.

Color

Color Specifications

Examples of ODS logo color usage. Black (K100) is the primary logo color, while a white reversed version may be used when background conditions prevent the use of black.

As a general rule, the logo must only be rendered in the colors specified below.
Please note that the colors shown in this manual may vary depending on printer models, paper stock, and other conditions. Always adhere to the specific color values listed.

Color Palette

Color palette used for the ODS brand. The palette consists of four primary colors and four accent colors: Pure Black (#000000, CMYK: 0,0,0,100, RGB: 0,0,0), Soft Sand (#b2ada2, CMYK: 0,5,12,41, RGB: 178,173,162), Cool Gray (#e9e9e9, CMYK: 0,1,1,13, RGB: 233,233,233), Light Cloud (#ffffff, CMYK: 0,0,0,0, RGB: 255,255,255), Deep Teal (#002f3a, CMYK: 76,0,19,87, RGB: 0,47,58), Ocean Blue (#145c7a, CMYK: 90,63,42,0, RGB: 20,92,122), ODS Orange (#cc5d3b, CMYK: 20,75,78,0, RGB: 204,93,59), and Warm Clay (#d7baab, CMYK: 18,30,30,0, RGB: 215,186,171).

Our color palette features a calm, sophisticated tone designed to evoke a sense of deep trust and intelligence, reflecting the core values of the ODS brand.
Using these colors for key brand elements—such as text, illustrations, and backgrounds—strengthens our visual identity and creates a more memorable brand experience.
While we strongly encourage using this primary palette, we understand that unique use cases may arise. If a specific scenario requires a color outside of this selection, you may adjust or extend the palette, provided the colors remain harmonious with the established brand tones.

Backgrounds & Contrast

Examples of approved logo usage on different background colors. Black logos should be used on light backgrounds and white logos on dark backgrounds, while low-contrast combinations should be avoided.

The standard application for the logo is black text on a white background.
The reversed version (white text on a black background) should only be used when a white background is not feasible.
It is highly recommended to maintain a contrast ratio between the logo and the background that falls within the recommended range.

Usage Violations & Prohibited Alterations

Examples of incorrect logo usage. The logo must not be stretched, compressed, rotated, split, cropped, decorated with effects, altered with gradients, or broken across multiple lines.

Typography

Brand Font (Latin Typography)

Typography sample of Inter, the recommended Latin typeface for the ODS brand, showing Bold, Medium, and Regular weights selected for readability and visual consistency with the brand identity.

For all text elements outside of the official logo and logotype, we recommend using Inter to maintain visual harmony with the latest version of the ODS logo.

Highly optimized for body text, Inter offers exceptional legibility. Its design ensures text remains clean and readable even at smaller sizes without blurring or overlapping. Furthermore, it guarantees cross-platform consistency across Windows, Mac, and iOS, displaying the exact design intended by the creator regardless of the user's viewing environment.

The official brand notation rules for Open Data Spaces (ODS)

  • Be sure to use the full notation, “Open Data Spaces (ODS)” the first time you mention it in any document or material.
  • After the first use, you may use “ODS” for later references in the same document or section.
  • Generic or lowercase forms, such as “open dataspaces” or references without “(ODS)” are not recognized as part of the ODS brand. This rule does not apply to file names, logos, or other cases with specific requirements.
* “Open Dataspaces” on this website refers to a new-generation distributed data management approach and its constituent concepts. Its design draws on the original dataspace papers in the U.S. (Franklin et al., 2005; Halevy et al., 2006) and data mesh (Dehghani, 2019; Dehghani, 2022).
