Attribute Card. Trust Anchor Comment
powerUsageEffectiveness 0..* ownedBy Power usage effectiveness (PUE) is a ratio that describes how efficiently a computer data centre uses energy; specifically, how much energy is used by the computing equipment (in contrast to cooling and other overhead that supports the equipment). PUE is the ratio of the total amount of energy used by a computer data centre facility to the energy delivered to computing equipment. The measurement is annually according to ISO/IEC 30134-2:2016 or EN 50600-4-2.A decimal number equal or greater than 1.0 is expected. For data centres and server rooms with a planned IT capacity at or below 2MW, energy consumed for office space, ancillary building space, and general usage may be excluded from PUE calculations. For this case, exclusions have to be mentioned.
waterUsageEffectiveness 0..* ownedBy Water usage effectiveness (WUE) is used to measure data centre sustainability in terms of water usage and its relation to energy consumption. It is calculated as the ratio between water used at the data centre (water loops, adiabatic towers, humidification, etc.) and energy delivered to the IT equipment. WUE will be measured using the category 1 site value, per ISO/IEC 30134-9:2022 standard.
waterType 0..* ownedBy Breakdown of the types of water used. Potable water is free from contamination and that is safe to drink or to use for food and beverage preparation and personal hygiene, in adherence to ISO/IEC 30134-9:2022.Freshwater is water having a low concentration of dissolved solids, in adherence to ISO 14046:2016. Greywater is wastewater with a low pollution level, no faecal matter, and reuse potential, in adherence to ISO 12056-1:2000. Blackwater is wastewater with significant pollution level without reuse potential, or recycled blackwater that has gone through tertiary treatment, in adherence to ISO 12056-1:2000.Seawater or brackish is water with significant salinity, in adherence to ISO 14046:2016.
climateType 0..* ownedBy Cool climates are those that are at or below a cooling degree day measurement of 49.99 based on annual data in 2019 for the NUTS 2 Region compiled by Eurostat. Warm climates are those that are at or above a cooling degree day measurement of 50.00 based on annual data in 2019 for the NUTS 2 Region compiled by Eurostat.

Personal Data Protection Regimes Gaia-X strives to contribute compliance with the protection of personal data, i.e., privacy. Gaia-X envisages its implementation internationally, whilst not neglecting its European sources.

Conformity with specific requirements deriving from different regimes protecting personal data will be subject to respective Labels. Nonetheless, it is considered significant added value, to allow Customers to filter Service Offerings by applicable regimes.

Thus, Service Offerings shall be able to identify Personal Data Protection Regimes in their respective Self Description. Such identified regimes do not entail any trusted or verified statement of compliance.

Non-exclusive list of Personal Data Protection Regimes:

The participant may wish to refer to ISO/IEC 27701 as a tool for comparing the various data protection regimes.

To enable interoperability, it is strongly recommended to refer to the options provided in the Gaia-X Registry. The Gaia-X Registry will allow for the possibility to select one or several of such regimes, as well as the possibility to add additional regimes. Maintenance of the registry shall regularly assess the individually identified regimes and - where appropriate - add such regimes to the pre-defined list of Personal Data Protection Regimes.

10.5 Interoperability, Portability, Switchability and Intellectual Property Protection (experimental)

While the format of the attributes is not yet defined, the sections below give insights about the future requirements.

Interoperability

This covers how the service offering can communicate with another service, such as making or responding to requests.

The aim of the future attributes is to provide:

  • a list of agreements in place with other service providers to ensure interoperability between systems
  • a list of URL to interoperability capabilities and transparency documentation

See ISO/IEC 19941:2017-5.2.1 for a description of the facets that need to be addressed.

Data Portability

This refers to the porting of data (structured or unstructured) from one cloud service to another, public or private.

Note: Data portability will inevitably be limited to Customer Data and a subset of Derived Data as determined by contract, privacy regulations, etc. See the ServiceOffering.dataAccountExport attribute.

The aim of the future attributes is to provide:

If a Gaia-X service offering includes multiple cloud services with different data portability capabilities, it is expected to have separate Self-Descriptions for each type of data portability capability.

Note 2: The SWIPO codes of conduct do not cover all cloud service categories (e.g. there is no specific SWIPO Code for PaaS), so it is not possible to mandate this attribute for all services.

See ISO/IEC 19941:2017-5.2.2 for a description of the facets that need to be addressed.

Application Portability

This refers to the porting of customer or third party executable code from one cloud service to another, public or private.

Note: Application portability is highly complex, especially when it comes to identity management, licenses, access control lists, privacy controls, transfer of credentials, etc.

The aim of the future attributes is to provide:

  • a list of URL pointing to a declaration of adherence such as SWIPO Code of Conduct
  • a list of URL pointing to a declaration of whether and how the application license can be switched to another service provider

If a Gaia-X service offering includes multiple cloud services with different data portability capabilities, it is expected to have separate Gaia-X Credentials for each type of data portability capability.

Note 2: For SWIPO Code of Conduct:

  • This can apply to executable code within an IaaS virtual machine instance, or code that can be executed within a larger SaaS application (such as scripts or SQL stored procedures).

  • This code of conduct does not cover all cloud service categories (e.g. there is no specific SWIPO Code for PaaS), so it is not possible to mandate this attribute for all services.

See ISO/IEC 19941:2017-5.2.3 for a description of the facets that need to be addressed.

Switchability

This refers to moving a customer’s account from one service provider to another, including the change of contracts and necessary technical changes.

Service switching is highly complex. Moving a customer to another cloud application provider requires identifying a destination which is in the same broad category of cloud service offering, and where the common functionality offered by the original service and the destination meets the minimum business needs of the customer wishing to switch. Since all services evolve constantly this is a moving target, and each customer will have different criteria. In addition, there can be considerable legal issues to be addressed. This includes the “policy” facets of data and application portability as described in ISO/IEC 19941:2017, but also the unique specifics of contracts and any possible implications for security and this continued compliance with privacy and data protection regulations. Responsibility for each stage of the switching process (including security, liability, and privacy compliance) will need to be determined and agreed upon in advance by all parties.

The aim of the future attributes is to provide:

  • a list of URL pointing to a declaration of whether and how a cloud service contract can be switched to another service provider
  • a list of URL pointing to required or available policies for switching
  • a list of URL pointing to a declaration of whether and how the Identity and Access Management function can be switched to another service provider

Note 1: At present, there do not seem to be any established Codes of Conduct or other frameworks that cover these aspects.

Intellectual Property Protection

The term Intellectual property (IP) refers to unique and value-adding creations of the human mind. IP enables the granting of property-like rights over new discoveries, new knowledge and creative expressions. IP relates to but is not limited to know-how, products, processes, software, data, and artistic works. The rights resulting from various forms of IP are referred to as intellectual property rights (IPR). IPRs provide ownership, i.e. the capacity to grant the IP usage rights (licensing), to assign the IP and rights to exclude third parties from using what is protected by the owner. Trust is paramount in the willingness of partners to collaborate and share information. IPRs can ensure the confidence of the partners that their knowledge capital and investment will be respected in the frame of acknowledged context and therefore that the use of the information shared will remain in the agreed context for the agreed duration. IPRs can exist in the form of a Patent, Utility model, Copyright, Trademark, Industrial design, Geographical Indication or Trade Secret (see WIPO and ISO 56005:2020(en))

In the context of the Gaia-X Trust Framework, IP can be declared on Service Offering, PhysicalResource, SoftwareResource and / or DataResource level.
