Automated Deep Linking

Good morning DaveNet!  Permalink to Good morning DaveNet!

It's been almost a week since I last wrote, I've been working on Frontier, that's been taking almost all my working cycles, except for the time I've been enjoying with the company of our membership on discuss.userland.com.  Permalink to It's been almost a week since I last wrote, I've been working on Frontier, that's been taking almost all my working cycles, except for the time I've been enjoying with the company of our membership on discuss.userland.com.

This last week has been incredible on our servers. The goodwill and intelligence and positive spirits have been amazing. We've tackled some difficult issues, and have stayed on track, no flames, very little invasiveness, mostly just happy people being smart. In their power, not whining about how someone let them down. OK. Let me correct that. At least not *all* of the messages have been whining and powerless. (I've even posted a few of these, expressing my frustration at wanting to buy a new PC that works and being powerless to do so!)  Permalink to This last week has been incredible on our servers.

In the background I've had a DaveNet piece in progress about syndication and aggregation. It's a very long piece, and it's been difficult for me to ship it because the issues are so complex. So instead I'm going to break it into smaller pieces and hope to have the whole area covered by the end of the month. There's something new going on, and it touches on some sensitive issues like who owns your home page -- you or the web?  Permalink to In the background I've had a DaveNet piece in progress about syndication and aggregation.

These days when I expose an issue it gets better coverage than in the old days. Three recent examples:  Permalink to These days when I expose an issue it gets better coverage than in the old days. Three recent examples:

1. The missing Microsoft Instant Messaging spec was first reported here in DaveNet. While the other news sources focused on the real-time battles between AOL and Microsoft (a legitimate story) we focused on Microsoft. Their story had a huge gaping hole. They were calling for AOL to open up their servers, but Microsoft's servers weren't open! A few days later, an announcement came from Microsoft that they would provide the specification in two weeks, and this morning it was released . Loop closed. From here it will be interesting to see if any compatible software is offered from other developers.  Permalink to 1. The missing Microsoft Instant Messaging spec was first reported here in DaveNet.

3. And finally, we've been reporting on antique software, the re-releases of VisiCalc , Dennis Ritchie's C compiler, the early Borland languages and the Living Videotext outliners . This resulted in coverage from the Washington Post, the London Sunday Times, the San Jose Mercury-News, and continuing coverage on the MacInTouch website.  Permalink to 3.

I mention these things because it's important to note success. It's not always like pissing in the wind. Sometimes when an issue is raised there are next steps and (in my humble opinion) good things happen.  Permalink to I mention these things because it's important to note success.

Do you mind if other websites continually read the HTML of your home page, break it up into individual headlines and links to stories, repurpose the URLs to point thru their servers, and distribute those links to people who want to read your news, along with news from many other sources?  Permalink to Do you mind if other websites continually read the HTML of your home page, break it up into individual headlines and links to stories, repurpose the URLs to point thru their servers, and distribute those links to people who want to read your news, along with news from many other sources?

This is not an idle question -- because there are several sites, some operating out of public view, that are running "story scraper" agents, that do exactly this. The sites they visit are the most popular news sites. To my knowledge, few if any of them have asked for the permission of the sites the scrape.  Permalink to This is not an idle question -- because there are several sites, some operating out of public view, that are running

We've engaged in discussion with some of the agents, some of the discussion has been respectful and positive, and some of it hasn't. I don't have much doubt as to whether it's fair or legal. I think it is unfair, and while I'm not a lawyer, judge or jury, I also think if one of the target sites objected and sued, the scrapers would be forced to stop.  Permalink to We've engaged in discussion with some of the agents, some of the discussion has been respectful and positive, and some of it hasn't.

On the other hand, there's been very little awareness of this issue. If the scrapers sent a request for permission, would the question get any consideration? It's my hope, with this article, that that process can begin now.  Permalink to On the other hand, there's been very little awareness of this issue.

In my opinion, it's clearly OK to link to a story on another site as it relates to a story I'm writing, or a subject I believe my readers are interested in. For example, it would be fair for me to point to the InfoWorld article where they reversed their position on deep linking, or to the Washington Post article about antique software.  Permalink to In my opinion, it's clearly OK to link to a story on another site as it relates to a story I'm writing, or a subject I believe my readers are interested in. For example, it would be fair for me to point to the InfoWorld article where they reversed their position on deep linking, or to the Washington Post article about antique software.

But, again in my opinion, it would *not* be fair for me to write a script that reads the home page of the San Jose Mercury-News, pulls off links to all the articles and the headline text and emails them, mixed in with links scraped from the New York Times home page, to a list, unless the Mercury-News and the Times had given their permission.  Permalink to But, again in my opinion, it would *not* be fair for me to write a script that reads the home page of the San Jose Mercury-News, pulls off links to all the articles and the headline text and emails them, mixed in with links scraped from the New York Times home page, to a list, unless the Mercury-News and the Times had given their permission.

The collection of stories on a home page, in my opinion, is a creative work. It's intellectual property, and is protected if there's a copyright notice on the home page. That's why the copyright notice is there -- to claim ownership, and to claim the right to determine how the information and ideas on the page, as a collection, are used.  Permalink to The collection of stories on a home page, in my opinion, is a creative work.

There is a line here, on one side of the line, we're quoting legitimate sources. On the other side, it's theft of intellectual property. It is my belief that at least some of the current scraper engines are on the wrong side of the line.  Permalink to There is a line here, on one side of the line, we're quoting legitimate sources.

Now the proponents of scraping point out that what they're doing is exactly what the search engines, Alta Vista, Excite, Google, et al, are doing.

Why I don't scrape  Permalink to Why I don't scrape

Enter RSS, an XML-based format for delivering to agents exactly the information that the scrapers are deriving from the HTML source of the websites. I've written about RSS before, my company has made a substantial investment in it, we co-designed the format with Netscape, and we've built software on both sides of RSS, a content management system that generates RSS, and an aggregator that collects it. I believe RSS is the right way to go for the following reasons.  Permalink to Enter RSS, an XML-based format for delivering to agents exactly the information that the scrapers are deriving from the HTML source of the websites.

I believe RSS is the right way to go for the following reasons.

First, I prefer to build on a format that's used solely for syndication, so the webmaster's intent can't possibly be misunderstood. If you have an RSS file that's registered with my syndication engine, you clearly want me to aggregate it. There's no other purpose for an RSS file.  Permalink to First, I prefer to build on a format that's used solely for syndication, so the webmaster's intent can't possibly be misunderstood. If you have an RSS file that's registered with my syndication engine, you clearly want me to aggregate it. There's no other purpose for an RSS file.

Second, by storing the information in RSS, there's no mistaking a non-news link for a news story. Have you ever used a search engine to search for a story on one subject and have it return twenty hits because they contained links to the story? With a separate syndication file, again, there's no mistaking what a link is about. Only news stories belong in a RSS file, not links from the template for the HTML rendering.  Permalink to Second, by storing the information in RSS, there's no mistaking a non-news link for a news story.

Third, we can extend RSS in the future to include other important information. For example, The Motley Fool, which covers publicly traded companies, wants to include a set of ticker symbols with every story. This makes perfect sense for their kind of content, but would not be needed for a site that covers a set of open source development projects. By starting fresh with a new format, just for syndication, we'll have more room to expand the format in the future to respond to opportunities in the market.  Permalink to Third, we can extend RSS in the future to include other important information.

My recommendation, if you want to disseminate links to your stories thru the new channels that are developing, make a small investment by producing a parallel version of your home page in RSS format and let us know where it is:  Permalink to My recommendation, if you want to disseminate links to your stories thru the new channels that are developing, make a small investment by producing a parallel version of your home page in RSS format and let us know where it is:

Our channel list is public, so any competitive aggregation engine can read the list, and churn your links thru their engine. We may profit at some point in the future from an economic system that rewards us, and our affiliates, for bringing traffic to your site. We already have competition, from Netscape, and there's sure to be more of that, because this is a valuable service and there's lots of room for diversification.  Permalink to Our channel list is public, so any competitive aggregation engine can read the list, and churn your links thru their engine.

So here's the summary. If you run a popular site, you're probably being scraped right now. This is not a someday issue, it's a right-now issue. If you want your links spread far and wide, consider supporting RSS. If you don't want that to happen, make your intent clear.  Permalink to So here's the summary.
