meta-data

<data> /me't*-day`t*/, or combinations of /may'-/ or
(Commonwealth) /mee'-/; /-dah`t*/ (Or "meta data")
noun: Data about data. In data processing, meta-data is definitional data that provides information about or documentation of other data managed within an application or environment.

For example, meta-data would document data about data elements or attributes, (name, size, data type, etc) and data about records or data structures (length, fields, columns, etc) and data about data (where it is located, how it is associated, ownership, etc.). Meta-data may include descriptive information about the context, quality and condition, or characteristics of the data.

Not to be confused with Metadata.



raw data

noun: unanalyzed data; data not yet subjected to analysis

Now, what is the context of this in Halo map terms. I mean, if you can extract the actual model from the "meta-data", what would be considered "raw data"? I am confused on this, and dmauro and Grenadiac said that this is what is hindering further SP injecting. What IS raw data?

EDIT:
Ok...

What is metadata? New
Offsets point to metadata. The metadata holds all the information, and optionally points to "raw" data. Raw data would be texture bitmaps, sounds, models, etc.

so... if a model is "raw data" How can we:

• 1. extract it from meta-data currently?
  2. extract it as raw data?
  3. inject (or rebuild with) into a different map?

I must be confused. I am.

OK -

The metadata for a model contains pointers to RAW data as well (vertices and indices)

In order to import a model, the metadata and the RAW data both have to be updated.

The metadata contains things such as Bones and Attachments (things that describe more how the model works rather than it's physical structure) and the Raw data contains the actual vertices and indices that make up the model.

Another example, is sounds. The metadata contains things such as the sample rate and the length of the sound, and the actual RAW sound data is stored in a different location in the map - which is pointed to by the sound's metadata.

Dunno if this helps or not

Yeah, that helped.

Is it even possible to extract raw data in raw format? Like binary format?

And is it possible to put that data into a map with a tool? Or does this have to be done manually?(which would suck).

I assume that projectiles have no raw data then, because... well, i dont know why.

Just trying to understand everything.

All data is binary

And yeah of course you can put it into a map - that's what you're doing when you inject models, bitmaps, and sounds.

Anything that has a texture, sound, or model has raw data - including projectiles.

Hey MonoxideC, this is a little off topic.. But why is ur rating a Grunt if u made Halo Map Tools?

I rarely post anything

cause he doesnt have the time to get 500+ post.

AH, so you have to actualy inject raw data? It doesnt get extracted and rebuild automatically?

Thanks for your replies, I appreciate the aquired knowledge.
