Problems that i ran into using Apache SIS
Hy,
I am newbie to Apache SIS,
Below are the issues that i ran into
========================================
1.The link below contains an example on how to use the command line
interface,however the link used to extract metadata throws 400,kindly
provide a valid one.(the link is now apparantly fixed my Professor Mattman)
*http://sis.apache.org/command-line.html
<http://sis.apache.org/command-line.html>*
2.Tried running the sis-console.jar after building the source using maven
*F:\sis_source\apache-sis-0.5-src\sis-0.5\application\sis-console\target>java
-ja*
*r sis-console-0.5.jar*
*--------------------------------------------------------------*
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/sis/util/l
ogging/MonolineFormatter
at org.apache.sis.console.Command.main(Command.java:230)
Caused by: java.lang.ClassNotFoundException:

... 1 more
3.Also i found this link provided my Proffesor Mattman was very useful to
run the sis.jar on windows which could be updated on the Apache SIS WIKI
http://svn.apache.org/repos/asf/sis/trunk/application/sis-console/src/main/artifact/README
Kindlt correct me if i was wrong.

For any AbstractMetadata object, you can get the types with the
following code:
AbstractMetadata metadata = ...,
MetadataStandard standard = metadata.getStandard();
Map<String,Class<?>> standard.asTypeMap(metadata.getClass(), KeyNamePolicy.UML_IDENTIFIER, TypeValuePolicy.ELEMENT_TYPE);
The TypeValuePolicy argument controls which kind of information you want
when the property is a collection. For example if a property type is
Collection<Citation>, then:
* With TypeValuePolicy.PROPERTY_TYPE, you get Collection.class.
* With TypeValuePolicy.ELEMENT_TYPE, you get Citation.class.
By the way, the MetadataStandard class also give you other methods like
asValueMap(...), which is the same as the asMap() method that you
already used but giving more control for example on what to return when
the property is null or empty. There is also asNameMap(...) if you need
to perform some mapping between the ISO 19115 names and the JavaBeans
names, or asInformationMap(...) for information like a sentence
summarizing the metadata, and whether a value is mandatory or not.

Hy,
I was able to extract the MetaData using the asMap() method of
defaultMetaData Object
=============================
Map<String,Object> hashMap= defaultMetadata.asMap();
========================
I am able to print the key Value pairs as below
------------------------
characterSets
[UTF-8]
contacts
[Responsible party
├─Role……………………… Resource provider
└─Party
└─Name…………… UCAR/NCAR - CISL - ACADIS
]
......
However the API doc describes the asMap() method returning a
HashMap<String,Object>.I need help in identifying the Object returned
by each key which would aid me in using theier setter() and getter()
methods.
Kindly let me know where i could get the list of Objects in the Map,I
could identify *Citation* as one of them.

Hello Gautham
Great that it worked!
For reading metadata: if the goal is to read metadata not only from XML
document, but also from other sources (currently only NetCDF), then I
would suggest the following:
import org.apache.sis.storage.DataStore;
import org.apache.sis.storage.DataStores;
...
try (DataStore ds = DataStores.open(input)) {
Metadata md = ds.getMetadata();
}
where 'input' can be a File, URI or any other type documented there:
http://sis.apache.org/apidocs/org/apache/sis/storage/DataStores.html#open-java.lang.Object-
Once you have the Metadata object, the getter methods allow to fetch
various information (or just do a System.out.println(md) to see what is
there). The "Aggregation hierarchy" column in the table in the following
page may be useful:
http://sis.apache.org/apidocs/org/apache/sis/metadata/iso/package-summary.html

Hello Martin,
Could you guide me as to which classes would i have look into since i need
to extract MetaData.
I am basically trying to build a .iso19139 parser for Tika using Apache SIS.
I am trying look into the Java API doc for the MetaData Package,but i need
a starting point as to how files are read in Apache SIS.
The Test Cases looks a little vague for me.

Hello Martin,
That works...in extracting the sis.jar from the source .
Thank you !!!

The reason is that the Apache SIS project is divided in many modules.
The "sis-console.jar" file is only the very last one in the chain; it
needs other modules for its working. There is different way to fix the
problems (e.g. run with Maven, use Maven "assembly", etc.). Would you
mind trying the following one?
After a successful build, execute the following command:
mvn org.apache.sis.core:sis-build-helper:dist --non-recursive
It should create the following file:
target/distribution/apache-sis-0.5.zip
Just unzip this file in any directory you like. If you were on a Unix
system, you could run directly the "bin/sis" executable. But on Windows,
we did not yet had volunter for writing a ".bat" file. You would have to
unpack the file manually:
unpack200 --remove-pack-file lib/sis.pack.gz lib/sis.jar
Then you should be able to execute directly that lib/sis.jar file, as it
contains all needed dependencies in a single file. Please let me know if
you encounter any issue.

Yes, you should find the same README file (with only different version
number) in the above-cited ZIP file. It could be use for completing the
wiki, if there is any volunter for taking care of the wiki?
