Sadly, Nifty Box has reached the end of the line. The developer has decided to pursue his true passion of working in the space industry, and Nifty Box will no longer be updated. The positive side of this is that the software is now available for free. For more information about the switch to freeware and how to transition your data out of Nifty Box, see the 1.3 blog announcement.

Tags is compatible with OpenMeta tagging apps like Leap, Default Folder X, or the newly released Punakea and is my favorite solution for tagging files after the fact (Default Folder X being the best option for tagging them as you first save them). Of course, you should be aware of the downsides to OpenMeta; as powerful as Tags and similar programs are, they aren’t something you should use without being aware of how they’re accomplishing their magic.

For more information about Punakea’s 1.0 release and subsequent move from free to shareware, see the blog posts on the first 1.0 release candidate, final pricing, and the 1.0 announcement. Release notes are also available.

Leap 2 is available for $59 with a 10 day demo, or $19 for owners of Leap 1 (to get the upgrade price, install Leap 2, launch it, and click the “Upgrade Now…” button for instructions). For more information, see the release notes.

I highly recommend Default Folder X even if you have no interest in OpenMeta (it’s a fantastic utility), but this release is basically a must-have for anyone trying to setup an OpenMeta-driven tagging system. For more details about the release, see the Default Folder X release notes.

For more information, see the Tag Folders release notes, MarsEdit 2.3 blog announcement, EagleFiler 1.4.5 blog announcement, and the Evernote 1.3 Mac blog announcement. Tags does not currently have up-to-date release notes online.

For more information about the update, see the release notes.

Fresh is one of those fantastic pieces of software that targets a common problem (”where the heck is that file I was just working on?”) and provides a simple, elegant solution that you can start using within seconds of downloading the program. Even if you’re uninterested in the tagging features (which I admit I’m personally unlikely to use; I prefer Tags), Fresh is an application that will slip easily into your workflow, likely making you wonder after a day or two how you ever lived without. Fresh offers a 21 day free trial, and costs $9 to register.

For more information, see the Together release notes or EagleFiler 1.4.4 blog announcement.

This turns out to be only half the story, however, and should you be a developer or user considering OpenMeta (or Tags) as a solution for your tagging needs you need to use it with eyes open. Although the technology OpenMeta uses is completely on the level, the way in which it achieves instant Spotlight availability is based on exploiting Spotlight’s preferential treatment of metadata that is identified as coming from Apple. This doesn’t mean that you should swear off OpenMeta and Tags (I’m still using them), but before you go tag-crazy you definitely need to consider the risks.

How does it do that?!

OpenMeta uses a technology called extended attributes to store and retrieve tags. Extended attributes (or xattr as they are often referred to by those in love with tech-speak) are a way for third parties or users themselves to add arbitrary metadata to files. Using extended attributes for tagging is entirely legitimate; the reason that they haven’t been used for generic tagging software before is that extended attributes are not indexed by Spotlight unless the program creating them registers them via a Spotlight importer, which means that the only program that will know about the special tagging extended attribute will be the program that created the tag.

Unfortunately, any given file can only have one Spotlight importer, which is usually the program that created the file. Clearly it isn’t feasible for a piece of tagging software to convince all the various developers whose files might be tagged to add support for their tags in their importers, so the typical route for adding information to the Spotlight index is out. (Thanks to Michael Tsai for clarifying this for me.)

OpenMeta gets around the Spotlight problem by identifying its tag attribute as coming from Apple. Spotlight automatically indexes extended attributes placed in the Apple namespace, and OpenMeta exploits this by quietly writing its tags into that namespace.

This is a problem because Apple doesn’t support other programs writing information to their namespace (the expected and sanctioned behavior is for programs to create their own unique namespace). Since Apple doesn’t support it, OpenMeta may or may not continue to work the way that it does now with subsequent updates to the operating system, and tag data may or may not be preserved.

OpenMeta (although possibly not Tags) does take steps to ensure that your information is backed up. In the event of extended attributes getting wiped for a file (which can occasionally happen if other programs are buggy in their use of extended attributes), OpenMeta stores backups of your tags in your Library folder. This, however, does not address the problem that OpenMeta is injecting information into an area that is reserved for Apple’s use.

So should I use OpenMeta?

Whether you should use OpenMeta is a question both developers and users should ask themselves before blindly adopting the technology. On the one hand, it has significant benefits and at long last offers a standardized way for programs to share tagging information with one another and the system without relying on Spotlight comments. On the other, the program is exploiting unsupported aspects of the operating system and can thus offer no promises about its future viability.

Michael Tsai of EagleFiler fame is the first developer I know of to have been willing to frankly discuss the downsides and specifics of OpenMeta’s implementation, and over the course of a long and wending forum discussion he recommends that OpenMeta change its focus from storing tags in an Apple namespace to storing tags in an OpenMeta-specific namespace available to all tagging programs with duplicate storage in the Apple namespace offered as an option for those to whom Spotlight integration is worth the potential downsides. For developers, I agree with Michael. Were I developing an app of my own that used tagging, I would be leery of relying on a framework that forced me to write to an unsupported namespace with no alternative, supported method for data storage.

For users the question of whether or not to use OpenMeta or Tags is more a matter of personal needs and preferences. If their functionality feels as much like magic to you as it does to me and you’re comfortable with using technology that isn’t officially supported by Apple, then by all means tag away. If you are using tags in a mission critical environment, you may want to think carefully about whether OpenMeta is for you but for most users the risk of data loss is extremely low.

Although I haven’t created a full-fledged system yet, I’ve slowly been developing a use for Tags which uses tags as supplemental information, pairing it with Hazel where I can to enable automatic sorting of tagged files into my standard folder hierarchy. I wouldn’t recommend using OpenMeta to try and replace a folder structure, but by utilizing it to add information I can have a richer store of metadata without being hamstrung if an OS update for some reason broke OpenMeta.

Whether OpenMeta will work for you or not should be based not just upon how great the product seems but also how comfortable you are with the methods being used behind the scenes.

My hope is that as OpenMeta and Tags gain traction, Apple will finally take note and address the problem of third party extended attributes having no way to get into the Spotlight index. Whether that happens or not, however, is impossible to predict; time will tell if OpenMeta is ahead of the curve or if it will ultimately go the route of SpotMeta.

For more information about the specifics of how OpenMeta does its thing, I highly recommend reading some of Michael Tsai’s posts in the aforementioned Ironic Software forum discussion. Although the thread ranges pretty far afield, some of the early information offers a very specific look at what OpenMeta is doing, and there are some interesting suggestions for alternative ways the software could go about achieving its various goals.

Unfortunately, the release notes don’t appear to be published anywhere online, but you can find them if you run the auto-update for the software (assuming you have it installed). If it’s not already on your computer, then now is as good a time as any to try it out.

HoudahSpot 2 requires Leopard, and is available for $25 with a 14 day free trial. Like other Spotlight enhancers, HoudahSpot gives you an easy way to construct and save complex searches without needing to rely on Apple’s less-than-ideal tools. If you’ve been as miffed at FileSpot’s apparent abandonment, then HoudahSpot definitely deserves your attention.

Aside from its extremely pleasant interface, Fontcase offers a surprisingly wide spread of features for a 1.0 release, including importing smart groups and so forth from Linotype’s FontExplorer X, local network sharing of fonts, the ability to print font previews, and more. Although the lack of any sort of Adobe plugins for auto font activation may make the program less appealing for true power users, Fontcase is a very appealing option to those like myself who need a better tool than Font Book but aren’t interested in spending an arm and a leg. Fontcase is available for a 14 day trial, and costs €35 / $46, with family and business packs available as well.

The exciting part about OpenMeta is that developers finally have a standardized way to assign and read tags on files (other than the less-than-ideal Spotlight comment hack of yore) which has the potential to free users from getting tied down to a particular solution. Aside from Tags and Deep (the first of which is compatible with OpenMeta, the second of which was the first program to use it), MailTags is also in the process of joining the OpenMeta bandwagon (not available in public builds yet, unfortunately). Hopefully software like Together, EagleFiler, and others of that ilk will also begin to incorporate OpenMeta, allowing users to tag and find files across the system and their various tagging programs without needing to keep all of those programs running.

The best news, however, is that besides being beautiful and so easy to use my tech-challenged grandmother could probably figure it out, Tags doesn’t use Spotlight comments or any other such hackery to accomplish its tagging. It instead uses extended attributes in a way that is compatible (or possibly identical) with OpenMeta, the open source tagging framework recently released by Ironic Software and incorporated into their photo tag browser Deep. For anyone who has been frustrated with the numerous limitations of Spotlight comment tagging, this is fantastic news indeed. Tags is available as a free trial from the Tags website, and when you’re ready to buy is priced at $29.

Some of my personal favorite features of The Hit List include the tabs (which essentially allow you to save snapshots of the sidebar and navigate between them, something which Things is sorely lacking), the wonderful notebook-paper inspired themes, and the in-depth and easy to get into keyboard navigation. If OmniFocus or the recently released Things don’t quite scratch your task management itch, The Hit List will be well worth checking out. According to its early testers, The Hit List is stable enough for daily use despite being in beta and not yet feature complete. If you fall in love with The Hit List you can preorder it for $49.95; the price after release will jump to $69.95, and it is completely free during the public preview. For more information and to download the application, visit the Hit List public preview announcement.

Things’ visual appeal should be obvious, but there’s also some recently added features worth noting. One of my favorites is that Things has always sorted tasks based on the tags you’re filtering by, but as of the release candidates the Today view doesn’t segregate tasks by project so you can organize tags by priority across projects simply by tagging them. Other note-worthy features since I last posted about Things are a refined interface, global searching across the entire library, an iPhone app that at last supports tags, and a much clearer delineation between projects and areas. I strongly recommend Things for anyone who finds OmniFocus too complex and TaskPaper too limiting. Things is available for $49.95; for more information about recent new features see the release notes.

The downside to the first public beta is that it doesn’t actually have much in the way of tagging support. There’s a place for tags in the Get Info window, but you can’t edit them (the contents currently defaults to the groups for a document). However, tagging (and presumably auto-tagging, given DevonThink’s long dedication to auto-sorting) is definitely on the radar for the final release. For more information about what’s new in DevonThink 2.0 and to download see the release notes and DevonThink 2.0 page. The first public beta will expire at the end of January, and upgrade options will be made available at the DevonThink website soon (they have announced, however, that users who purchased DevonThink 1.x after July 1, 2008 will receive a free upgrade to 2.0). DevonThink 2.0 requires OS 10.5.
