Section: Primary String

This question set collects basic information regarding the string that is being applied for (for example, a-label, meaning, script). If the applying entity opts to designate a replacement string, it must answer the same set of questions for the replacement string from the AGB Question Set 5 on.

AGB Q116. Applied-for Primary String (ASCII Label)

xio

AGB Q118. What is the meaning/definition of the applied-for gTLD string?

Provide the meaning, or restatement of the string in English, that is, a description of the literal meaning of the string in the opinion of the applying entity. If there is no literal meaning in English (for example, a brand name or a proper noun without a translation) simply state "No English Translation"

Coined technical abbreviation read as "x-IO": "x" in its technical sense of "cross" (cross-platform, cross-origin) and "IO" for input/output. The string denotes cross-system input and output, i.e. data exchange, particularly for AI applications.

AGB Q120. Phonetic Representation

Provide a representation of the string according to the International Phonetic Alphabet.

/ˌɛks.aɪˈoʊ/

AGB Q121. As per Section 3(d) of Specification 11 of the Base Registry Agreement, a registry operator of a “generic string” may not impose eligibility criteria for registering names in the TLD that limit registrations exclusively to a single person or entity and/or that person’s or entity’s “Affiliates” (as defined in Section 2.9(c) of the Registry Agreement). “Generic String” means a string consisting of a word or term that denominates or describes a general class of goods, services, groups, organizations or things, as opposed to distinguishing a specific brand of goods, services, groups, organizations or things from those of others. Confirm that the applied-for string is not a “generic string” in which the applying entity intends to limit registrations exclusively to a single person or entity.

Confirm the statement using a checkbox.

true

AGB Q133. What is the mission and purpose of the applied-for gTLD?

1. Describe the mission and purpose of the applied-for gTLD, including the intended registrants and users, and the related activities that have been or will be carried out to achieve this purpose. 1a. If applying for a variant of an existing gTLD, please also describe the mission and purpose of the existing gTLD, including the intended registrants and users, and the related activities that have been or will be carried out to achieve this purpose. 2. Explain how this purpose is sustainable over time.

The mission of .xio is to give the software integration layer a namespace that names what it does. The string is read as ""x-IO"": ""x"" in its established technical sense of ""cross"", as in cross-platform, cross-origin or cross-compile, and ""IO"" as the ordinary abbreviation for input/output. Together they denote cross-system input and output - the point at which one system sends data to, or receives data from, another. The string is applied for and will be operated as an open namespace in that plain descriptive sense. Registrants are the organisations and people who build and operate machine-to-machine interfaces: providers of artificial intelligence and machine learning services, including model and inference providers, agent and orchestration frameworks, retrieval and vector infrastructure, and evaluation or observability tooling; API-first software vendors; integration, middleware and automation platforms; data pipeline and streaming operators; robotics, sensor and connected-device vendors; cloud and hosting providers; open source projects; and individual developers. Users are the people and the software that reach those addresses: engineers reading documentation and configuring endpoints, and the client libraries, services and automated clients that resolve a name in order to call an interface. The clearest present case for the string is the machine-facing surface of AI systems. A model or inference provider exposes an endpoint that client code calls. An agent framework discovers and calls tools over declared interfaces. A retrieval or vector service is reached by a pipeline rather than by a person. An evaluation or observability service receives traces emitted by a running system. In each case the address is written once into documentation or configuration and is thereafter used by software, not typed by a human. That is the position .xio names: an address whose audience is another system. Holding those endpoints separately from a marketing domain also allows an operator to version, relocate or transfer an interface without touching its public site. The gTLD has it's use as Interfaces are named poorly today. An endpoint is typically a subdomain of a company's marketing domain, which ties a long-lived technical address to a name chosen for commercial reasons and tells the reader nothing about what sits behind it. A short top-level namespace whose term is precisely ""cross input/output"" resolves that mismatch: name.xio is compact, readable to the audience that matters, and self-describing. The demand for short, io-terminating names is already demonstrated: developer-facing services have used a two-letter country-code TLD for this purpose for more than a decade, without connection to the territory it designates. .xio offers the same brevity inside the gTLD space, under a Registry Agreement and ICANN policy. .xio is open. There is no eligibility screening before registration; any person or entity may register, through any ICANN-accredited registrar. Registrations are not limited to the applying entity or its affiliates. A .xio name is attached to a running interface: referenced in documentation, embedded in client configurations, written into third-party integrations. Names in that position are renewed for as long as the service exists, because changing them costs more than keeping them making the market for the gTLD sustainable.

Section: Safeguard Identification

This question set collects information related to determining whether certain Safeguard Public Interest Commitments (Safeguard PICs) are required for the applied-for gTLD string. See Section 7.8.2.3 Safeguard PICs. Answers to these questions will inform assessment by ICANN on whether and which Safeguard PICs must be incorporated in the applicable Registry Agreement (RA) if the string proceeds to delegation. The answers themselves will not automatically make such a determination.

AGB Q164. Will people see a domain name as more trustworthy because it is registered in your TLD? Think about how people around the world will understand the TLD string(s) in the application, including literal and informal meanings in different languages and regions.

1. When answering the questions, apply criteria by considering the meaning of the requested TLD string in the following contexts: a. Literally as described in the application b. Literally in any other language in which the string is a recognized word or phrase. c. Informally in any language or regional variant, where alternative meanings exist. 2. If the proverbial “reasonable person” who understands the relevant context believes that the question should be answered ‘yes’, then the answer is yes.

AGB Q165. Is it likely that consumers will face significant risks if domain names in the TLD(s) in the application are abused? Think about how people around the world will understand the TLD string(s) in the application, including literal and informal meanings in different languages and regions.

AGB Q166. Would people generally think that this TLD will be used by entities that require strict licensing or accreditation to do business? Think about how the TLD string(s) in the application will be understood around the world, including both literal and informal meanings in different languages and regions.

AGB Q167. Would most people think that (domains in) the TLD(s) in the application are used for activities that require regular government reporting, inspections, and oversight in various countries? Think about how the TLD string(s) in the application will be understood around the world, including both literal and informal meanings in different languages and regions.

AGB Q168. Could people reasonably believe that (domains in) your TLD will cause or lead to harassment, harm, aggression, complaints, criticism, distress, or embarrassment? Think about how the TLD string(s) in the application will be understood globally, including different languages and cultures.

1. When answering the questions, apply criteria by considering the meaning of the requested TLD string in the following contexts: a. Literally as described in the application b. Literally in any other language in which the string is a recognized word or phrase. c. Informally in any language or regional variant, where alternative meanings exist. I-2. If the proverbial “reasonable person” who understands the relevant context believes that the question should be answered ‘yes’, then the answer is yes.

AGB Q169. Would most people think that the TLD is used for something usually done by governments? Think about how the TLD string(s) in the application will be understood globally, including different languages and cultures.

1. When answering the questions, apply criteria by considering the meaning of the requested TLD string in the following contexts: a. Literally as described in the application b. Literally in any other language in which the string is a recognized word or phrase. c. Informally in any language or regional variant, where alternative meanings exist. I-2. If the proverbial “reasonable person” who understands the relevant context believes that the question should be answered ‘yes’, then the answer is yes.

AGB Q170. Are you proposing to include one or more of the Safeguard Public Interest Commitments (Safeguard PICs) in the Registry Agreement (RA) voluntarily regardless of ICANN’s Safeguard Assessment outcomes?

Select Yes or No. Notes: 1. ICANN will evaluate whether an applied-for gTLD string requires one or more Safeguard Public Interest Commitments (Safeguard PICs) to be included in the Base RA). 2. In addition to the Mandatory Public Interest Commitments (PICs) that must be included in each Base RA, a subset of Base RAs must include Safeguard PICs based on ICANN’s Safeguard Assessment. See Section 7.8.2.3 Safeguard PICs. 3. Applying entities for TLDs that are not found to require Safeguard PICs can elect to add them to the applicable Base RAs voluntarily to, for example, further their business objectives, help address issues or concerns that are raised or could be raised with respect to their applications, or avoid the need for the evaluation and implementation of customized Registry Voluntary Commitment (RVC). See Section 7.8.3 Registry Voluntary Commitments (RVCs).

Section: Registry Voluntary Commitments (RVCs)

This question set collects information related to any Registry Voluntary Commitments (RVCs) that the applying entity is submitting. The decision to submit an RVC is typically voluntary, except for those recognized by ICANN to resolve an objection or to address GAC Consensus Advice. See Section 7.8.3 Registry Voluntary Commitments for more information.

AGB Q172. Are you proposing to include one or more Registry Voluntary Commitments (RVCs) in the Registry Agreement (RA) that are unique to your applied-for string?

1. Select Yes or No. 2. In addition to Safeguard Public Interest Commitments (PICs), an applying entity will be permitted to propose one or more Registry Voluntary Commitments (RVCs) to provide additional safeguards with regard to the registry operator’s operation of an applied-for gTLD string. See Section 7.8.3 Registry Voluntary Commitments (RVCs). 3. RVCs are separate from Community Registration Policies. See Section 7.8.3 Registry Voluntary Commitments (RVCs) and Section 7.8.4 Community Registration Policies for more information. If you are applying for a Community gTLD, please submit the Community Registration Policies by answering Questions 150-155. However, if you propose to include additional Registry Voluntary Commitments in the RA beyond the Community Registration Policies, you may answer "yes" and proceed to answer the following questions. 4. You are encouraged to consider whether there are other means, separate from including commitment(s) in the Base RA, that could be used to further your business objectives or help resolve any anticipated or actual issue(s) raised regarding the applied-for gTLD string or application. See Section 7.8.3 Registry Voluntary Commitments (RVCs). Notes: If you select “yes” to this question, you are required to pay the conditional Registry Commitments Evaluation fee, and commitments that are approved by ICANN will be included in Specification 11 of the applicable Base RA as specific voluntary public interest commitments as contractual obligations.

Section: Brand & Code of Conduct Exemptions

Section: Additional Information and Supporting Materials

This question set collects any additional information that the applying entity would like to provide, including any supporting materials.

AGB Q222. If the applying entity wishes to provide any additional information or supporting materials that the applying entity believes may be of interest to the public or relevant to the application, please include them here.

1. An applying entity may use this response field to submit any additional, optional information or documentation that the applying entity believes enhances understanding of its application or may be of interest to the general public. This could include, but is not limited to, the applying entity’s: a) Individual registry policies; b) Separate agreement with a third-party to fulfill certain commitments; c) Terms of use; d) Additional Community Registration Policies not intended for RA inclusion; e) Other materials that clarify the applying entity’s mission, values, or intended use of the gTLD. Notes: 1. This question is optional and for informational purposes only. 2. The information provided here will not be evaluated as part of the application, or be contractually binding on the applying entity. 3. All submissions to this question will be posted for the public to review and comment.

Additional information - reading of the string and scope of the application. .xio is a coined technical abbreviation. It is not a dictionary word and it is not a brand. It is applied for on the reading set out in the response to the mission and purpose question: ""x"" for ""cross"" and ""IO"" for input/output. The applying entity claims no exclusivity over either element, and this application does not seek Specification 13 status or any Code of Conduct exemption. The applying entity notes that a share of the intended registrants build artificial intelligence services. The application does not propose that the Registry Operator assess, certify, approve or regulate those services, and no such capability should be inferred from the string. The Registry function is naming. Conduct at the second level is addressed through the abuse provisions of the Registry Agreement, applicable Consensus Policies and Temporary Policies, and the standard rights protection mechanisms, applied reactively after registration. The applying entity operates the namespace as an open TLD, available to any registrant through any ICANN-accredited registrar, on published and non-discriminatory terms
