<joakim> on my way in again
<joakim> Chris is guilty!
<joakim> No no, we need him
<scribe> scribe: pchampin
minutes of the last meeting approved
joakim: any volunteer for next week (2010-02-09)?
pchampin: the scribe list is actually on the main page
Daniel: we don't have a scribe for next week
Thierry: I can't next week, but I volunteer for the following week (2010-02-16)
<tmichel> right my rerets for next week.
<chris> I will not be available either next week
Florian: I will scribe next week
John: I sent an email to the
... full professor in South Korea
... chair or co-chair of several orga: IETF, IEEE...
... autonomic(?) communications
... expertise: knowledge engineering
Somebody: ring, ring, ring
<chris> I will follow the phone conf through IRC
John: ... (covered by ringing)
<tmichel> joakim is noisy ;-)
<chris> sorry for the noise
joakim: what is your interest in the WG?
john: teaching graduiate level
course on semantic reasoning
... about 1/ covering various knowledge representations
... 2/ decision making (inferencing)
... e.g. using ontologies
... 2 PhD students interested in knowledge engineering
... worked for Motorola in the advance used of annotation
... for context-aware functionality
... I'm known for network management
... but have never been satisfied by the tools used
... so looking for better ontologies, better semiotics in the network management field
... volunteer to take action items or participate in editing documents
joakim: thanks for joining
john: was invited by Daniel
joakim: is Ashish here?
joakim: apparently not
<trackbot> ACTION-124 -- Felix Sasaki to check - everybody responsible for a format: add a column describing syntactic information ("data types", see cable lab column "Type") to his table -- due 2009-06-16 -- OPEN
<trackbot> ACTION-196 update scribe list closed
joakim: sent an email proposing to use XML as an input format
pchampin: didn't have time this week to have a look at it
<scribe> ACTION: pchampin to read and sumarize test-methodolofy for the group [recorded in http://www.w3.org/2010/02/02-mediaann-minutes.html#action01]
<trackbot> Created ACTION-208 - Read and sumarize test-methodolofy for the group [on Pierre-Antoine Champin - due 2010-02-09].
pchampin: two problems for implementations:
1/ extract the legacy metadata from the original format
2/ map that metadata to the vocabulary
joakim: the testsuite should be about 2/
<joakim> if we provide the legacy md in an artifical format the test will not be fair
<chris> I agree with joakim that the testsuite should be about 2/
pchampin: I agree too
<chris> We wouldn't suggest a specific XML parser either to extract information from the XML metadata
pchampin: but I don't think its is practical to separate the two in an implementation
<chris> so I dont think it would be good to specify specific software libraries for the embedded metadata
pchampin: anyway, implementations will *have* to do 1/
pchampin: assume that an
implementation does the mapping correctly
... but extracts the metadata in a wrong way
... would we like it to pass the tests?
... because in a real situation, it would not give the expected results
joakim: the metadata formats are
various: XML-based, binary...
... there are several cases to deal with
<joakim> the test should deal with the md as in the "WILD!"
pchampin: yes, but I suggest we provide "ecological" metadata rather than artifical metadata
<chris> I agree, it is the responsibility of the implementation to get the embedded metadata out a file and to map it accordingly
<chris> so this should be part of the testsuite
<chris> maybe we can make two different test suites, one for embbeded metadata and one for external metadata?
pchampin: I am favorable to providing the "extracted" metadata
pchampin: just for the
implementors to check that they are extracting the metadata in
a consistent way
... but they are expected to run the test on the "real" format
<joakim> Should we provide the test with both media file and extracted md?
pchampin: furthermore, it would allow us to detect errors in the test suites
florian: I like the idea, but will the W3C like it?
pchampin: I'll tell you when I have read the document
<joakim> Chris can you call in again?
florian: suggested that the Caliph project could be used to extract metadata
joakim: I had a quick look at
their web page
... it's interesting
florian: the focus is on
... though they have support for extraction
... and it is opensource
... currently worling on cophir
florian: photos from flickr
... extract MPEG7 features
... with a link to the image
... we are working to setup a crawler
... and also extract DC metadata
joakim: where do you get the MPEG-7 features?
florian: they are provided by the
... we could use this as a base for our testsuites
... this is a student work, so I don't know when it will be finished
<Daniel> Florian: what application this project is targetting for ?
florian: just building the
... to provide the images with DC and MPEG7 metadata
daniel: what about exif?
florian: out of scope for the student, as exif can be extracted directly from the jpeg
joakim: so the task of the student is to fill in the gap?
<chris> the semantic gap?
florian: yes, we extract legacy
md from the flickr API, and map it to DC
... and MPEG7 (?)
<joakim> not semantic gap!
florian: I'll write to Chris about it :)
<florian> Chris, we only use the id of an image to extract metadata using the flickr api - this extracted metadata will be stored in DC and MPEG-7
<scribe> ACTION: florian to share his image metadata with the group (when he has it) [recorded in http://www.w3.org/2010/02/02-mediaann-minutes.html#action02]
<trackbot> Created ACTION-209 - Share his image metadata with the group (when he has it) [on Florian Stegmaier - due 2010-02-09].
<florian> and the IDs are stored in the COPHIR test suite wit the mpeg-7 low level features
florian: last week of april
daniel: we already had a straw poll, there should not be problems
<tmichel> I will participate
daniel: who is supposed to participate in the Seoul meeting?
<tmichel> to Seoul
<chris> I will be there
joakim: will online presence be possible in Seoul?
tmichel: shall I reserve a phone bridge?
<joakim> Chris will you join next telcon?
joakim: we will discuss the API document next week
