Issues with ASPATH from rib

Hello!

I'm trying to build mapping from IP to AS number with
bgpdump-1.4.99.15 and my custom toolkit.

So I downloaded dump
http://archive.routeviews.org/bgpdata/2015.11/RIBS/rib.20151128.0600.bz2
and trying to parse it with bgpdump.

For about 90% of full BGP table I'm getting correct values for ASPATH.

For example for my ASN 198068 I got:
TIME: 11/28/15 06:00:03
TYPE: TABLE_DUMP_V2/IPV4_UNICAST
PREFIX: 46.36.223.0/24
SEQUENCE: 55029
FROM: 147.28.7.2 AS3130
ORIGINATED: 11/11/15 18:25:25
ORIGIN: IGP
ASPATH: 3130 2914 9002 198068
NEXT_HOP: 147.28.7.2
MULTI_EXIT_DISC: 2
COMMUNITY: 2914:410 2914:1201 2914:2202 2914:3200 3130:380

But some prefixes I'm getting very strange ASPATH with ASN enclosed in
curly quotes.

For example you could look at:

TIME: 11/28/15 06:00:01
TYPE: TABLE_DUMP_V2/IPV4_UNICAST
PREFIX: 5.39.176.0/21
SEQUENCE: 5583
FROM: 147.28.7.1 AS3130
ORIGINATED: 11/13/15 08:02:15
ORIGIN: IGP
ASPATH: 3130 2914 3356 8530 {198753}
NEXT_HOP: 147.28.7.1
AGGREGATOR: AS8530 91.143.64.24
COMMUNITY: 2914:420 2914:1007 2914:2000 2914:3000 3130:380

How I should interpret this record "3130 2914 3356 8530 {198753}"? Who
are origin for this prefix 8530 or 198753?

After some time of digging to this data I got more strange example:

TIME: 11/28/15 06:00:06
TYPE: TABLE_DUMP_V2/IPV4_UNICAST
PREFIX: 69.43.64.0/18
SEQUENCE: 108538
FROM: 195.208.112.161 AS3277
ORIGINATED: 11/27/15 13:37:08
ORIGIN: IGP
ASPATH: 3277 3267 174 32432 {6939,46887}
NEXT_HOP: 195.208.112.161
AGGREGATOR: AS32432 38.88.209.254
COMMUNITY: 3277:3267 3277:65321 3277:65323 3277:65331

So I really haven't any ideas about this ASPATH: 3277 3267 174 32432
{6939,46887}.

Could you clarify both cases (with single and multiple AS numbers)
with curly quotes?
