Introduction – Making the News


Dopesheets

Information on the news story Description content (who, what, where, when, …) Administrative information (reporter, cameraman, …) Rights information (usage terms, copyright statement, …) Technical information (video format, audio format, …) …

Initially: plain text (cf. telex)

Currently: proprietary structured text (XML, e.g. NMS)

Future: international standardized structured text (XML)

IPTC’s NewsML-G2


Telex


Dopesheet Examples


NewsML-G2

International (industrial) standard approved by IPTC

(shortened) Timeline 1997: NITF 2000: NewsML 1.0, 1.1, 1.2 (too complicated and ineffective) 2008: NewsML-G2

Objectives NewsML-G2: Interoperability between providers and consumers Extensibility Clarity and compactness of the syntax Ease of storage Ease of processing for relational or object mapping New focus on “semantic” capabilities (Web 2.0 ready)

Automatic News Production

Now @ VRT: Classical broadcast: linear, 5 broadcasts a day On-demand (“ooit gemist”): replay of the linear broadcasts Web (“deredactie.be”): news clips, continuous updates

Linear broadcasts have a rigid structure E.g., 19h news

– Max 20 news items– Max 40 minutes

More content available than broadcasted News feeds (EBU/Eurovision, Reuters, …) Produced items never or only a few times broadcasted


Goals

Enable a news consumer to compose his own news programme Select only the news categories he is interested in

– e.g., national weather, international business, … Sort the news categories according to his personal relevance

– e.g., first sport, then business, then politics Specify the maximum duration of the news

– e.g., his commuting time is 30 minutes, so 30 minutes ofnews

Let him choose to receive unedited (“raw”) news materials/feeds– e.g., every news items about science & technology

Let him watch the news items offline– e.g., play his news on a mobile device, such as iPod Touch

Without interfering with current news production processes

Final remarks

By intelligently processing the available metadataautomatic personalized news bulletin generation is feasible

However, some “gaps” IPR management (now: free text – no automatic usage approval) category assignment for VRT news items item versioning (linking items)

Tools might solve some of these gaps
