Metadata Online Resources
I started to compile a list of online resources on metadata and other fun topics. This is a work in progress, and I'll probably update it by editing this post. Also, here's a link to a more complete Word document with more annotations and hyperlinks on additional worthy topics like examples of Digital Asset Management systems, conference archives, and a growing list of related stuff.
Here's a bit of what's in my evolving "resource document":
Open Source Public Broadcasting Online Resources
The case for shared metadata standards
FAQs for those of us who don't know what that means
In case you haven't followed recent developments in metadata (few have!) and didn't read Steven Vedro's article "Why metadata matters" in Current last September, you may feel as if you've missed a meeting on the subject. Consider this a make-up class. The article was commissioned by CPB.

PBCore: WELCOME TO THE PBCore Metadata Dictionary
The Public Broadcasting Metadata Dictionary Project is a cross-organizational, multi-disciplined effort to establish a standard for all public broadcasting content (radio and television), in order that metadata might be more easily exchanged between colleagues, software systems, institutions, community partners, individual citizens, etc. The Project will be a “touchstone,” a single, streamlined standard to which other database structures, including those of PBS, NPR, major producing stations, and other asset/content management systems will be “mapped.” It can also be used as a guide for the onset of an archival or asset management process at an individual station or institution.

NewsML: The International Press Telecommunications Council (IPTC)
The IPTC was established in 1965 by a group of news organisations including the Alliance Européenne des Agences de Presse, ANPA (now NAA), FIEJ (now WAN) and the North American News Agencies (a joint committee of Associated Press, Canadian Press and United Press International) to safeguard the telecommunications interests of the World's Press. Since the late 1970's IPTC's activities have primarily focussed on developing and publishing Industry Standards for the interchange of news data.
This site describes NewsML, “designed to provide a media-independent, structural framework for multi-media news.”

Dublin Core
The Dublin Core Metadata Initiative is an open forum engaged in the development of interoperable online metadata standards that support a broad range of purposes and business models. DCMI's activities include consensus-driven working groups, global conferences and workshops, standards liaison, and educational efforts to promote widespread acceptance of metadata standards and practices.

Web casting, or broadcasting over the internet, is a media file (audio-video mostly) distributed over the internet using streaming media technology. Streaming implies media played as a continuous stream and received real time by the browser (end user). Streaming technology enables a single content source to be distributed to many simultaneous viewers. Streaming video bandwidth is typically calculated in gigabytes of data transferred. It is important to estimate how many viewers you can reach, for example in a live webcast, given your bandwidth constraints or conversely, if you are expecting a certain audience size, what bandwidth resources you need to deploy.
To estimate how many viewers you can reach during a webcast, consider some parlance:
One viewer: 1 click of a video player button at one location logged on
One viewer hour: 1 viewer connected for 1 hour
100 viewer hours: 100 viewers connected for 1 hour…
Typically webcasts will be offered at different bit rates or quality levels corresponding to different user’s internet connection speeds. Bit rate implies the rate at which bits (basic data units) are transferred. It denotes how much data is transmitted in a given amount of time. (bps / Kbps / Mbps…). Quality improves as more bits are used for each second of the playback. Video of 3000 Kbps will look better than one of say 1000Kbps. This is just like quality of a image is represented in resolution, for video (or audio) it is measured by the bit rate.
