RSS Proponent Seeks Cooperation with Google

The Ongoing Debate Between RSS and Atom

For years, RSS has been the default choice for publishers looking to syndicate their content across the web. Its simple, human‑readable format and robust tooling ecosystem made it easy for bloggers, news sites, and data feeds to share updates in real time. In late 2003, however, a quiet shift began to take shape. A handful of developers and companies were championing Atom, a newer specification designed to address some of the limitations that had crept into the earlier RSS versions.

Google’s decision to switch its flagship blogging platform, Blogger, from RSS to Atom was a catalyst that pushed the two syndication worlds into the spotlight. Blogger, purchased by Google in January of the previous year, is the largest consumer‑facing blog portal on the internet. By default, every new post on Blogger was exposed via an Atom feed, and the platform’s API was built around that format. Google’s announcement was clear: Atom would be the new standard for all Blogger content, and it would be fully compatible with the AtomPub publishing protocol.

Because Atom is not backwards‑compatible with RSS 2.0, publishers who had relied on RSS feeds had to either maintain two separate feed streams or adopt Atom for the first time. That required changes to the feed’s namespace, the way entries are labeled, and the data validation process. The transition was not trivial, especially for smaller blogs that already had automated systems for parsing RSS.

One of the more visible examples of syndication is the way large news aggregators operate. Companies like Moreover.com gather headlines from hundreds of topics, then publish those headlines across a network of partner sites. Each headline links back to the full story on its original website. The entire system hinges on the reliability and consistency of the underlying feed format. When a new standard comes into play, every node in that network must adapt.

Because Atom is designed to be more machine‑friendly and to provide a stricter schema, it also offers a robust validation process. Feed validators such as those provided by the Atom Publishing Project can quickly flag errors that would otherwise cause downstream applications to fail. In contrast, RSS 2.0’s leniency means that malformed tags can slip through unnoticed, leading to broken feeds that frustrate both publishers and readers.

When Google announced its switch to Atom, the syndication community was split. Some welcomed the change, noting that Atom’s formal specification could reduce the inconsistencies that had plagued RSS for years. Others saw Atom as an unnecessary fork that would fragment the ecosystem further. The debate escalated because both formats promised different benefits: RSS’s simplicity and broad adoption, versus Atom’s strictness and alignment with modern web standards.

Beyond the technical considerations, the switch also had a commercial dimension. Google’s control over Blogger gave it leverage to influence how content was distributed. By adopting Atom, Google could encourage other publishers to follow suit, potentially giving its own infrastructure a competitive edge over traditional RSS‑centric services. The strategic implications were clear: whoever controlled the dominant syndication format could steer the flow of information and shape the way users discover and consume content.

Meanwhile, a notable voice in the conversation was Dave Winer, a developer who helped craft many of the web’s early standards, including RSS and XML‑RPC. Winer has long been a champion of the syndication ecosystem, arguing that content should remain free to move across platforms without proprietary lock‑in. His perspective added depth to the debate, as he has historically straddled the line between advocating for open standards and supporting business models that rely on them.

Winer’s engagement with the issue culminated in a public call for a truce between the RSS and Atom camps. He framed the conflict as a needless battle that could be resolved by collaboration, rather than competition. By inviting Google and other stakeholders to cooperate, Winer hoped to preserve the benefits of both formats while minimizing fragmentation. His proposition was not simply a technical fix; it was a call for the community to find common ground in a way that kept the internet’s content infrastructure stable and open.

Dave Winer’s Vision for Unified Syndication: A Seven‑Point Proposal

In a post that has become a cornerstone for those advocating for open syndication, Winer laid out a seven‑point manifesto. His goal was to create a new format that would honor the strengths of both RSS and Atom while fostering an inclusive, standards‑based ecosystem. The proposal is straightforward, yet it tackles a complex set of problems that have long plagued the syndication landscape.

Point 0 – Naming the New Format. Winer suggested calling the hybrid specification “RSS/Atom.” The name acknowledges both traditions and signals a blended approach. By using a familiar term, the community could recognize the continuity between existing feeds and the new standard. The name also sidesteps confusion that might arise from using a completely new label.

Point 1 – Minimal Departure from RSS 2.0. The new format would introduce as few changes as possible to the familiar RSS 2.0 schema. This means retaining most of the element names, such as item and title, while making only the adjustments necessary to accommodate Atom’s validation rules. The idea is to lower the learning curve for publishers who already publish RSS 2.0 feeds.

Point 2 – Leveraging Atom’s Strengths. One of Atom’s biggest advantages is its validator, which enforces a strict schema. By adopting Atom’s validation mechanisms, the new format would reduce the prevalence of malformed feeds. This feature would be especially attractive to developers who rely on reliable data streams to power applications, from news aggregators to social media timelines.

Point 3 – Open Governance via an IETF Working Group. Winer proposed that the new format be governed by an Internet Engineering Task Force (IETF) working group. Such a group would welcome anyone with an interest in improving syndication technology, from academic researchers to corporate developers. This inclusive model contrasts with the earlier, more siloed development processes and encourages broader participation.

Point 4 – Backwards Compatibility with RSS 2.0. The new standard would be designed so that any existing RSS 2.0 feed could be upgraded to the hybrid format with minimal effort. For example, adding a new root element or namespace declaration could be all that is needed. This approach would preserve the investments already made in RSS infrastructure while opening the door to the new capabilities.

Point 5 – A Distinct Top‑Level Element. In Atom, the top‑level element is called feed, which clashes with potential future formats that might also use that name. Winer suggested using rssAtom as the root element to avoid ambiguity. By giving the format a unique identifier at the highest level, parsers can quickly determine the feed type and apply the correct validation rules.

Point 6 – Open Spec and Future‑Proofing. Though Winer left this point open-ended, the intention was clear: the format should evolve to accommodate emerging needs, such as richer media attachments, multilingual support, and fine‑grained access controls. An open specification would allow the community to add extensions without breaking compatibility.

Point 7 – Community‑Driven Development. The final, implicit point in Winer’s manifesto was that the success of the new format would hinge on active community engagement. By inviting developers, publishers, and users to contribute, the format could adapt organically to real‑world use cases and avoid the pitfalls of a top‑down mandate.

Winer’s manifesto is more than a technical blueprint; it is an invitation to the syndication community to collaborate on a shared future. By blending the familiarity of RSS with the robustness of Atom, the proposal aims to keep the internet’s content ecosystem flexible and resilient. For publishers and developers who rely on feeds to distribute information, the idea of a unified, standards‑based format resonates strongly. Whether the industry embraces this vision remains a question, but the dialogue it sparked has already broadened the conversation around syndication and opened new avenues for cooperation.
