Definition of object attributes

Product

Homepage: Where you can find the product or the surrounding project or community.

Product name: Denomination of the product as given by its originators.

Product category: Classification of the product according to the Google Product Taxonomy given in the dropdown list.

Product description: What the product is about, e.g. if it is a tractor or a hair-dryer.

Project status: Whether the surrounding community is active or inactive. Does someone sell the item or develops the product further at the time? Rule of thumb: the community is considered inactive in case no activity (encompassing either product development or sales and marketing) can be detected on the website or the collaboration platforms used by the surrounding community within one year.

Contains original non-electronic hardware: Whether the product contains original non-electronic hardware components, that is, which have been developed within the project.

Contains original electronic hardware: Whether the product contains original electronic hardware components, that is, which have been developed within the project.

Contains original software: Whether the product contains software components, that is, which has been developed within the project.

Development stage: Defines the maximal maturity level achieved by one of the eventual versions of the product over time. Five maturity levels are defined in the order of increasing liability risk. (1) “Concept” - There is only a theoretical design that is still to be fully developed. No liability of the product originator applies. (2) “Prototype” - The early design phases have been completed and the first functional prototype has been built. No liability of the product originator applies. (3) “Production/DIY” - The product is fully defined and documented and can be replicated. No liability of the product originator applies. (4) “Production/Kit” - The product is sold by a commercial actor as a kit. Limited availability applies to the vendor. (5) “Propduction/Full product” - The product is sold by a company as a finished product. Full availability applies to the vendor.

Public CAD repository for non-electronic hardware: Where CAD files (computer aided design) or blueprints of the non-electronic hardware can be accessed online.

Public CAD repository for electronic hardware: Where CAD files (computer aided design) or blueprints of the electronic hardware can be accessed online.

Public code repository: Where the source code can be accessed online.

Assembly instructions: Where assembly instructions can be accessed online.

Bill of materials: Where the bill of materials (also named part list) can be accessed online.

Contributing guide: Where the guidelines for participation or a dedicated call for contribution are provided to potential contributors.

Editable CAD: Whether the CAD files released online are editable. CAD files are considered editable if they are released in their original format. They are not considered editable if they are only released in an export format such as PDF or STL which does not allow further modifications.

Editable assembly instructions: whether the published assembly instructions are editable. Assembly instructions are considered editable, if they can be edited in a Web 2.0 environment or downloaded as editable files. A file is furthermore considered editable if it is released in its original format. It is not considered editable if it is only available in an export format (such as PDF).

Editable bill of materials: Whether the assembly instructions released online are editable. Assembly instructions are considered editable if they can be edited in a web 2.0 environment or downloaded as editable files. A file is furthermore considered editable if it is released in its original format. It is not considered as editable if it is only available in an export format such as PDF.

License: Intellectual property licensing scheme used for the publication of the hardware.

Free redistribution: Whether the license applied to the hardware allows commercial usage of the published content. If no license applied, the criteria is set to false.

Open-O-meter: The open-O-meter is a simple scale from 0 to 8 where a product gets one point for each of the following aspects: 1) design files are published, 2) assembly instructions are published 3) a bill of materials is published 4) a contribution guide is published 5) the published CAD files are in editable format 6) the published assembly instructions are in editable format 7) the published bill of materials is in editable format 8) all this information is published under a license allowing commercial reuse.

License

Name: Denomination of the license as given by its originators.

Reference: where the terms of the license can be consulted.

Free redistribution: Whether the terms of the license allow commercial usage of the published content.

CAD Format

Name: Denomination of the CAD format as given by its originators.

Editable: Whether the format in which the CAD information is stored allows further edition. For example, export formats such as STL and PDF are not editable, i.e. critical information is lost in the export process (i.e. featured based design, constraints, parameters etc.). Native formats are considered as editable, as all information formalized in the design process is stored in the native file and can be retrieved by opening the file again.
