EML Protocol
Summary:
A set of fields that contains method, processing, and quality control
information.
Description:
eml-protocol is a set of fields that contains method, processing, and
quality control information. It may consist of paragraphs of descriptive
text that describes the methods to be employed, or optionally references
to literature citations that do the same. Likewise, descriptions of pre
and post processing of data files may be described within.
Example:
Please see the examples for the sub-fields.
Lineage:
Derived from EML 1.4: eml-status, and eml-quality modules.

Unique identifier
Summary:
The unique identifier of this metadata file or object.
Description:
The identifier field provides a unique identifier for this
metadata documentation. It will most likely be part of a
sequence of numbers or letters that are meaningful in a
larger context, such as a metadata catalog. That larger
system can be identified in the "system" attribute. Multiple
identifiers can be listed corresponding to different catalog
systems.
Example:
<identifier system="metacat">nceas.3.2</identifier>
Lineage:
The 'identifier' field is derived from the eml-dataset
meta_file_id filed in EML 1.4.

method information
Summary:
Information about the methods employed in collecting or generating
a data set or other resource.
Description:
The method field allows for repeated paragraphs of text that
describe the methodology for a project, experiment, or particular
data table. Likewise, a literature citation may be provided that
describes the methodology that was employed.
Example:
<paragraph>
1.Collect tissues from algae of interest.
</paragraph>
<paragraph>
a.We are currently collecting Egregia menziezii, Mazzaella
splendens, M. flaccida, Hedophyllum sessile, Postelsia
palmaeformis and Fucus gardneri.We stopped collecting
Neorhodomela larix and Odonthalia floccosa because they can be
heavily fouled and we feared that would skew the results.
</paragraph>
<paragraph>
b.We collect a 7-10 cm blade or branch from each plant. For
Egregia, try to sample small, young plants or take the base of
the blade. For Postelsia, take a few of the blades. The other
plants are small enough so a whole blade can be taken.

Processing Step
Summary:
Information on pre or post processing actions for a data set.
Description:
Step defines the quality control or quality assurance procedures
that were applied to the corresponding data file. For example,
a shell-script that 'greps' for an alpha-character within a
datafile that is supposed to contain only numeric characters
Example:
<paragraph>
2.Freeze tissues at -20C until they can be dried. Dry tissue in
drying oven (60C, at least 24h).
</paragraph>
<paragraph>
Grinding: All glassware and plasticware should be acid washed in
10% HCl. Place dried algal sample in plastic vial with ground
glass ball. For very hard to grind tissue such as M. splendens,
two balls may be used. Place vials in grinder. Only two vials can
go in the mill at one time. Grind for 2-5 minutes. Tissue should
be fine powder. Place ground tissue in small screw cap vials and
store in drying oven or dessication chamber.

Quality Control
Summary:
Information on possible errors or on the quality of a data set.
Description:
The qualityControl field provides a location for the description
of possible errors in a data set, or a description of the quality
of the data set based on the the processing steps or methods
employed in collecting the data.
Example:
<paragraph>
Once the data file is received, verify it's integrity by
comparing it's checksum with the pre-calculated MD5 checksum by
running the md5 command on the file. If they match, the file
transferred correctly.
