On the Importance of Standards
Standards, specifications, and recomendations—no matter what you call them, and
what meaning you give to which of those terms a particular document is given—are one
of the most important and most abused topics relating to communication, interoperability,
and product design.
This section is a mixture of commentary and collections of raw links, organized by topic. Not
every topic has commentary, but hopefully you will find even these simple lists of links to standards
helpful in your research, as I have.
Standards Topics I’m Researching
Standards Every Developer Must Understand
- XHTML, XML, CSS, XSLT
- The heart of the 21st Century Web.
- HTTP Content Negotiation
- Designed to let desktop computers, PDAs, TVs, and mobile phones access
the Web without needing different URLs. RFC 2068/HTTP 1.1 and
RFC 2295.
- Unicode 5.1.0
- Especially the UTF-8 encoding, which uses US-ASCII to represent
any character in the world.
- MIME Types
- The official repository for specifying the type of content transferred over the Internet.
- Official IANA Registry of URI Schemes
- This is the always-current registry of what URI schemes exist on the Internet. Key entries include
http (Web), ftp (FTP), mailto (E-mail address),
imap (E-mail server), rtsp (streaming video/audio), sip/sips (VoIP address),
tel (Dial a phone number), ldap (contact directory), h323 (H.323 address),
ipp (Internet Printing Protocol), and im (Instant Messaging).
- SIP/SIMPLE
- The Session Initiation Protocol is the IETF standard (RFC-3261, RFC-3515,
RFC 2976...) for IM and VoIP addresses, and should
co-exist along with E.164—the worldwide telephone numbering system.
- alpha image transparency
- The lack of support for alpha transparency, especially in PNG and TIFF files, makes creating
clean-looking Web sites, PowerPoint presentations, and other documents impossible or tedius.
- Data Matrix
- Public-domain 2D barcode, codified in the ISO/IEC16022 and MIL-STD-130L standards.
- IrDA & OBEX
- Infrared data transfer and object transfer over IR and Bluetooth for exchanging contacts, calendars, and more.
- vCard 3.0
- RFC 2425,
RFC 2426,
RFC 2739, and
RFC 4770.
- iCalendar
- An open standard for exchanging and publishing event and personal calendars, to-do lists, and free/busy time. RFC 2445,
RFC 2446, &
RFC 2447.
- SyncML
- An industry-standard Mobile Data Synchronization Protocol, for synchronizing contacts, calendars, etc. among computing devices.
- MPEG-4 Part 10 (a.k.a. H.264/AVC)
- The MPEG-4 Advanced Video Codec profile, used by Apple’s iChat AV,
which should be the primary videoconferencing encoding.
- FireWire 800
- The best replacement for serial, parallel, and SCSI ports.
