Thank you for considering contributing to the evolution of the iCalendar standard! Your proposal for a new iCalendar property is a valuable step in ensuring the continued relevance and utility of this widely adopted format for scheduling and calendaring data. To facilitate a thorough understanding and evaluation of your proposed addition, we kindly request that you furnish as much detail as possible. This comprehensive information will enable us to assess the item's potential impact, compatibility, and overall benefit to the iCalendar ecosystem.
Which Item Would You Like to Add?
Identifying the specific item you propose to add is the crucial first step. Please specify the exact name of the iCalendar component, property, or parameter you wish to introduce. For example, this could be ATTACH, MEMBER, or VTODO. Precision in naming ensures clarity and avoids ambiguity in subsequent discussions and evaluations.
Detailed Description
A comprehensive description is the cornerstone of your proposal. This section should delve into the intricacies of the proposed item, providing a holistic view of its purpose, functionality, and potential impact. The more detailed your description, the better we can understand the item's value and how it fits within the iCalendar framework. Consider the following key aspects when crafting your description:
Purpose and Use Cases
Clearly articulate the purpose of the item. What problem does it solve? What functionality does it introduce or enhance? Provide concrete use cases to illustrate the item's practical application. For instance, if you propose a new property for specifying meeting locations, detail how this property would be used in various scenarios, such as scheduling meetings across multiple locations or integrating with mapping services.
The purpose and use cases of any new iCalendar item are critical to understand its value. What problem does this item solve, or what new functionality does it introduce? To effectively evaluate your proposal, it's essential to provide concrete use cases that illustrate the item's practical application in real-world scenarios. These use cases should paint a clear picture of how the item would be used and who would benefit from it.
Consider the potential user stories associated with the item. For example, imagine a scenario where a new property is proposed for specifying the level of importance or urgency of a task within a VTODO component. A use case could involve a project manager using this property to prioritize tasks for their team, ensuring that critical deadlines are met. Another use case might involve a calendar application using this property to visually highlight urgent tasks in a user's agenda. By providing such detailed scenarios, you help reviewers grasp the item's tangible benefits.
Furthermore, it's important to outline the target audience for this item. Is it intended for general use across all iCalendar applications, or is it geared towards a specific niche or industry? Understanding the intended audience helps assess the potential adoption rate and overall impact of the proposed item. For example, a property related to healthcare scheduling might be highly valuable within the medical field but less relevant for other users. Describing the item's applicability to different contexts allows for a more nuanced evaluation of its usefulness.
Relevant Specifications and RFC References
Referencing existing standards and specifications is crucial for establishing the item's compatibility and adherence to established protocols. If your proposed item builds upon or extends existing iCalendar features, explicitly reference the relevant sections of RFC 5545 or other applicable RFCs. This demonstrates a thorough understanding of the iCalendar standard and facilitates a smoother integration process.
Referencing relevant specifications and RFC references is crucial for several reasons. First and foremost, it demonstrates that the proposed item aligns with the overall architecture and philosophy of the iCalendar standard. By citing specific sections of RFC 5545 or other related RFCs, you provide a clear context for your proposal and show that you have a solid understanding of the existing framework. This is particularly important for ensuring compatibility and avoiding conflicts with existing features.
RFC 5545, the primary specification for the iCalendar format, provides a comprehensive set of rules and guidelines for defining calendar data. When proposing a new item, it's essential to analyze how it interacts with the existing components, properties, and parameters defined in RFC 5545. Does your item extend an existing concept, or does it introduce a completely new one? How does it affect the overall structure and semantics of an iCalendar object? By explicitly addressing these questions and referencing relevant sections of the RFC, you provide a clear roadmap for reviewers to understand the item's place within the standard.
Furthermore, referencing RFCs helps establish the item's adherence to established protocols and best practices. The Internet Engineering Task Force (IETF), the organization responsible for publishing RFCs, follows a rigorous review process to ensure that proposed standards are technically sound and interoperable. By aligning your proposal with existing RFCs, you increase the likelihood of it being accepted and widely adopted. If your item deviates from existing standards, it's crucial to provide a compelling rationale for the deviation and explain how it maintains compatibility with existing iCalendar implementations.
Widely Supported or Experimental
Indicate whether the item is already in use by specific applications or if it is purely experimental. If the item has existing implementations, providing details about its adoption rate and any known issues can be beneficial. This information helps assess the item's maturity and readiness for standardization.
It's essential to distinguish between items that are widely supported in existing iCalendar implementations and those that are still experimental. This distinction helps in understanding the item's maturity, adoption potential, and the level of risk associated with its inclusion in the standard.
If the item is already in use by specific applications or platforms, it indicates a degree of real-world validation and practical utility. Providing details about these existing implementations, such as the applications that support the item, the number of users who are using it, and any feedback or issues reported by users, can significantly strengthen the proposal. This evidence demonstrates that the item addresses a genuine need and that it can be successfully implemented in a production environment.
For items that are widely supported, it's also important to consider the level of interoperability between different implementations. Do different applications interpret and handle the item in the same way? Are there any known compatibility issues or variations in behavior? Addressing these questions can help ensure that the item can be seamlessly integrated into the iCalendar ecosystem without causing fragmentation or confusion. If there are existing interoperability challenges, it's beneficial to propose solutions or guidelines for ensuring consistent behavior across different implementations.
On the other hand, if the item is purely experimental, it means that it's a novel concept that hasn't yet been widely tested or adopted. While experimental items can be highly innovative and potentially valuable, they also carry a higher level of risk. In this case, it's crucial to clearly articulate the rationale behind the item, the potential benefits it offers, and the research or prototyping efforts that have been conducted to validate its feasibility. Providing a detailed explanation of the item's design principles, implementation challenges, and potential limitations can help reviewers assess its suitability for inclusion in the standard.
Expected Behavior and Formatting Rules
Clearly define the expected behavior of the item and its formatting rules. Provide a precise description of how the item should be interpreted and processed by iCalendar applications. This includes specifying the data type, allowed values, and any constraints or dependencies on other items. A well-defined specification minimizes ambiguity and ensures consistent interpretation across different implementations.
A crucial aspect of any proposed iCalendar item is its expected behavior and formatting rules. This detailed specification ensures that different iCalendar applications interpret and process the item consistently, minimizing ambiguity and maximizing interoperability.
Start by precisely defining the data type of the item. Is it a text string, a number, a date, a time, or a more complex structure? Specifying the data type helps to ensure that applications handle the item's value correctly. For example, a date property should be formatted according to the ISO 8601 standard, while a numeric property might have restrictions on its range or precision.
Next, clearly outline the allowed values for the item. Are there any specific keywords or enumerated values that are permitted? Are there any constraints on the length or format of text strings? For example, a property that represents a status code might have a predefined set of valid values, such as "CONFIRMED," "TENTATIVE," or "CANCELLED." Specifying the allowed values ensures that applications can validate the item's content and prevent errors.
Furthermore, consider any dependencies or relationships between the item and other elements within the iCalendar object. Does the item require the presence of other properties or components? Does its value influence the interpretation of other items? Clearly defining these dependencies helps to ensure that applications process the item in the correct context. For example, a property that specifies the geographical coordinates of an event might depend on the presence of a location property.
Example
Providing a concrete example of the item as it would appear in an iCalendar file is invaluable. This allows reviewers to visualize the item in context and understand how it integrates with existing iCalendar structures. The example should be a valid iCalendar snippet that demonstrates the item's syntax, formatting, and usage.
An example iCalendar snippet is an indispensable part of your proposal. It provides a concrete illustration of how the item would appear within an iCalendar file, allowing reviewers to visualize its syntax, formatting, and usage in context. This practical demonstration is far more effective than abstract descriptions alone in conveying the item's essence and facilitating understanding.
The example should be a valid iCalendar snippet, meaning that it adheres to the iCalendar syntax rules and can be parsed by iCalendar applications. This ensures that the example accurately represents the item's intended form and doesn't introduce any confusion or ambiguity. If the item has complex formatting rules or dependencies, the example should showcase these aspects clearly.
The snippet should include the relevant iCalendar component (e.g., VEVENT, VTODO, VJOURNAL) in which the item would typically be used. It should also include any necessary surrounding properties or parameters to provide context. For instance, if you are proposing a new property for specifying the time zone of an event, the example should include a VEVENT component with other properties such as DTSTART, DTEND, and SUMMARY, as well as the proposed time zone property.
Within the snippet, highlight the proposed item clearly, perhaps using comments or annotations. This makes it easy for reviewers to identify the item and focus on its specific details. The example should also demonstrate how the item's value is represented, including any special formatting or encoding requirements. For example, if the item's value is a URL, the example should show how the URL is formatted and encoded according to iCalendar standards.
Additional Comments or Considerations
This section provides an opportunity to address any additional aspects of your proposal that haven't been covered in the previous sections. This might include implementation considerations, potential edge cases, compatibility concerns, or any questions you have regarding the item's integration into the iCalendar standard.

It allows you to proactively anticipate potential questions or concerns from reviewers and provide clarifications or justifications. This section can significantly enhance the completeness and persuasiveness of your proposal.
One important aspect to address here is implementation considerations. How would the item be implemented in iCalendar applications? Are there any specific challenges or complexities that developers should be aware of? Providing insights into the implementation aspects can help reviewers assess the item's feasibility and potential impact on existing systems. For example, if the item requires significant changes to parsing or rendering logic, it's important to acknowledge this and suggest possible solutions.
Another crucial area to consider is potential edge cases. Are there any unusual or less common scenarios where the item's behavior might be unclear or problematic? Identifying and addressing these edge cases demonstrates a thorough understanding of the item's potential limitations and helps to ensure its robustness. For example, if the item involves dates or times, it's important to consider how it interacts with different time zones and daylight saving rules.
Compatibility concerns should also be addressed in this section. How will the item interact with existing iCalendar implementations that don't support it? Will it cause any parsing errors or unexpected behavior? It's important to propose strategies for handling backward compatibility, such as defining a fallback mechanism or providing guidance on how applications should ignore unsupported items. This helps to ensure that the item can be safely introduced into the iCalendar ecosystem without disrupting existing applications.
By providing comprehensive information and addressing potential concerns proactively, you can significantly increase the chances of your iCalendar item proposal being accepted and adopted. Your contribution will help to enhance the iCalendar standard and make it even more valuable for scheduling and calendaring applications worldwide.
